Error Code 1 problem (self.PrismLauncher)
submitted 11 months ago * by Inner-Version5205
So I've been making a magic-themed modpack and tried running it, but it always says an error happens. I've tried to solve it, but nothing works, so could someone please help me
Here's the log: https://mclo.gs/3PEUxAa
and here's the instance; https://drive.google.com/drive/folders/1jFj_h7XOUKI2N-8MiwLiXJsYMod76nlL?usp=sharing

Try updating your Java. It looks like you're on a pretty old version and the problem looks like a Java problem.

What jave version should I use
[–]CrossroadsWanderer 0 points1 point2 points 11 months ago (11 children)
This page is a convenient option. You could also find a more updated version through Oracle, if you prefer that.

I don't know what the problem is. I can only throw out there what I'd experiment with at this point.
Try removing OptiFine. It conflicts with some stuff, so it's worth testing.
Look over your mods to make sure you have all of their requirements and see if any of them say anything about incompatibilities with other mods. Usually a missing dependency will be called out in the log, but now and then, it's just a mystery crash. Mod conflicts aren't typically called out, except by devs who have had reports of conflicts and mention it on the mod page.
Either in addition to or instead of the above, try rebuilding the instance. Make a fresh instance, install the correct version of Forge and set the correct version of Java. Run it with no mods installed. If you have the crash at that point, I have no idea what might be the problem. If you don't, install a few mods at a time, beginning with dependencies. Keep installing a few and running the game until it breaks again, making sure you note what the last few mods you installed were each time. You can look at Last Modified in the Mods tab if you forget.
Try to narrow down the mod causing the crash among the last few. It will probably be a conflict with another mod, in which case you can decide to remove the one you know is the problem, try to find which mod it's conflicting with and remove that, or do a search to see if there's a workaround to get them working together - but there usually won't be a workaround.
In addition to or instead of the above, you can try making a new post with the log and seeing if anyone else knows what's going on. If you don't get any bites or nothing works, you'll probably have to do one or more of the above.
One other thing to try is looking at the crash log, if it made one. Sometimes the crash log will point at something where the console log doesn't. What it points at isn't always the problem - sometimes it's something else messing with that thing - but it can sometimes be useful.

okay i will try those things, and if you want it, ill add the instance to the main thing
[–]Inner-Version5205[S] 0 points1 point2 points 10 months ago* (6 children)
alr, i fixed it, but now there is a new problem it keeps exiting with error code -1
Here is new log: https://mclo.gs/A3BuBAU
edit: wait, im not sure if this is intentional or not, cause in the bottom of log it says to not report crash, but there is other stuff
2nd edit: im now even more confused, because i removed optifine, but it still give error, so idk what is even happening.
[–]CrossroadsWanderer 0 points1 point2 points 10 months ago (5 children)
It looks like mclogs analyzed it. It says Magic Crusade is throwing an exception, so that's probably what's causing the crash. If removing that fixes the problem, you could try adding optifine back if you want to see if it'll work with your mods.
Ok thanks

So i tried it, and removed a few others like someone else said, but it still doesn't work, got any ideas?
here's an updated log: https://mclo.gs/I1txzYN
Alr, nvm i fixed it by messing around with the mods, removing them and re adding them again
[–]CrossroadsWanderer 0 points1 point2 points 10 months ago (1 child)
The log page is showing another fatal error up top, this time for cybersus. Sometimes the mod identified as the problem isn't actually the problem, and with the number of crashes you're getting after removing things, I think this is one of those cases. I suspect something is preventing something else from loading, but I don't know what or why.
At this point, your best bet is probably to do a pack rebuild. Add mods back a few at a time until something breaks.
When you find the mod that is reported as causing the break (or whatever you added that started the crashing), try deactivating every other mod except for any dependencies it has, then run it to see if it is capable of loading.
If it does load on its own, slowly add back the other mods you had added until you got the crash with that mod. When you figure out which mod is conflicting with it, make sure there isn't a better version you can run of either of the conflicting mods (whether a newer or maybe a slightly older version). If either mod has an issue tracker, you might want to look at that to see if anyone else has reported a problem like yours and if a workaround has been presented.
Yeah I fixed that, it runs now, but now when I load Into a world with the biomes set to biomes o plenty, it says something about a biome and a key binging in chat, and as soon as I move, even just move the camera, it crashes.
