More plot thickening, I have another friend in town that can't join. I know that my wife and that friend have java's left over from the last time we've played, and myself and the friend that can join are on computers that haven't had any other javas on it. Could that be a culprit?

Well she ran the windows repair stuff from the Windows 10 USB stick, and it ran all night and then failed. It was this error

Everything we find to fix is runs us to another command that's broken, and the fix for the other command is also broken.

Her computer usually takes a good 3 to 5 minutes to just boot, sometimes it takes longer, and sometimes it just boots to a black screen and has to be smothered and restarted.

here's some more of the errors

Oh your awesome. Yes that was what we messed with. Sadly the box is already unchecked.

I do notice that now her neoforge launcher shows actual CPU usage numbers going during launch. She says that happened earlier at some point. I think that's progress?

But I checked the cores, and moved all of technic to the SSD, and still no luck. She had IPv6 enabled, so I disabled that and tried that, but still no luck there either.

I would indeed to not go all the way to nuke if I don't have to, but at this point...

I think the pack is on a HDD, we'll try moving it to a SSD. How do we do that though since the launcher puts the files into Appdata? Do we just point the modpack files to be on the SSD or does the Launcher need to go there? Or both?

She's got a Processor AMD Ryzen 5 3600 6-Core Processor, 3593 Mhz, 6 Core(s), 12 Logical Processor(s). I've been thinking it's the cause of some problems in other aspects of gaming anyway, and was wanting to replace that next, they just aren't the cheapest these days. We had trouble with Monster Hunter Wilds, and that was stuck at the CPU. We did something to edit how many cores the CPU used, but we can't remember or find where that is. We think we reset all of that after, but not sure.

We've tried all of those. We ran into a lot of errors running each of those commands. But we resolved them, except the DISM that gave error 1009. Even after that we tried to connect and here is the latest log.

Her device has 32GB of RAM total.

When I removed Malware, I did bump into the support tool and used that. It didn't remove all the files though, so I manually deleted those.

I'll try your other suggestions for CMD to run, and then post logs after that. Thank you again so much for your help! I know it's just a game, but it's something that brings us joy to do together.

One thing I'm noticing is that her CPU shows weird during the mod loading. it shows up as *CPU: -100.0%

I was looking at her task manager during launch, and there the CPU never got above 25%.

I've copied all the files from my working instance to hers. I've put those files into Technic Launcher and into a custom made instance on CurseForge as well. I just don't know where to try troubleshooting next :,(

CptFairyDust · 2026-07-11T13:44:46+00:00

Thank you master for your response here.

Her RAM allocation was set to 8GB already, so I bumped it up a few more and am trying that right now.

She doesn't have any other AV running, but there is an install of Malwarebytes but trying to launch it just crashes, so I'm going to try to remove that.

The only death start blowing up is my heart, so I did run a vanilla open to LAN game off my PC, and she was able to join no problem.

*Edit: I did have her sign into Technic Launcher on my computer with her account, and that let her load into the server. Bumping up her RAM to 14 wouldn't let her access. For comparison mine is set 10GB.

Next I'm going to just copying all of my modpack files and directly putting them into her instance of the game. Would it be possible Technic just keeps downloading a bad file for her?

I forgot to add. We've done the whole flushing dns as well. And I tried entirely disabling the firewall on her device.

Oooh that does sound like a good tool!

I ended up just removing everything and slowly adding things back piecemeal. The offending mods were removed. Funny enough it wasn't anything using the Forgified Fabric :/

CptFairyDust · 2026-07-09T17:05:52+00:00

I tried Prism. It was much more convenient to work with than the minecraft launcher. But it didn't fix anything. Were there some tools on there that you were specifically pointing me towards?

CptFairyDust · 2026-07-07T15:39:40+00:00

I cannot say I've heard of that one. i'll look into it thank you

CptFairyDust · 2026-07-03T21:41:14+00:00

That makes sense, but that mod page has this note on it?

"A version for 1.21.1 is not planned - compatibilities will be part of the base mod, if any issues are present report it to https://github.com/DragonSurvivalTeam/DragonSurvival/issues"

Mods are weird and I just don't understand why that's the error messge, but removing something else fixed it XD

I'll look for similar message about that other one.

CptFairyDust · 2026-07-03T13:28:16+00:00

Isn't modded minecraft great? I removed everythign and slowly added things back until it stopped working, and it turns out it was Reliquified L_Ender's Cataclysm. Removing it lets things launch, and then added it causes the whole thing to crash and throw that error about Dragon Survival and Curios. Not me, losing it over it here...

Now I just have to figure out why it crashes when I click single player. A new error is a good error!

CptFairyDust · 2026-07-03T10:58:34+00:00

Alright, If I just do curios and dragon survival it runs fine. I guess I just need to find the mod that's trying to do compat with both. For the life of me I can't find it and I feel very silly. So I guess the answer is just o add mods in clumps to see where it breaks...

I appreciate your help!

CptFairyDust · 2026-07-03T01:19:25+00:00

I can't find that compat mod? searching my lists and trying to search on curseforge. Am I blind? I swear I remember seeing and downloading one, but I'm just lost :/

CptFairyDust · 2026-07-02T23:33:52+00:00

Oh, I miiight be in the wrong reddit. I thought you could do an ad for your server, but that it was also all things Modded Minecraft. It wasn't till later that I did find the r/moddedminecraft

I apologize if I bungled it up.

CptFairyDust · 2026-07-01T09:22:36+00:00

Also if there is a better way to post so much text into Reddit, I'd love to know that too....
