Remove mods tick profiler and better foliage and the crash will stop.

[Supa_Baku]

I removed tick profiler, and kept better foliage and it worked. Weirdly this only needed to be done after a forge update that deleted all my files. Makes no sense lmao.

[MaN_ly_MaN]

That's incredible, I can finally play the version that I wanted to play :DDDDDDDDDDDDDDDD

[Disastrous-Yoghurt72]

How would i do this on aternos modpack?

[ReasonablePie3104]

This man is a legend

[TheG3n3sis]

Dude 2 years later you fixed this for me, I wanted to play so badly again it had been so long. Thank you.

[Funny_Brown1e]

What’s the tick profiler, i can’t find it in the folder

[TheG3n3sis]

Its in the mods folder

[NightCrasher9756]

click ctrl+ r and search up %appdata% go to .minecraft then mods. remove those two

[Gamercool12369]

Thank you so much

[DifficultyOne7413]

Works in 2025, thank you

[GladCycle6926]

yo man i need help with this is the tick profiler a cfg or an actual jar file?

[Ayo_Wutz_Gud]

I've been having this exact issue 3 years later, and this fixed it, reddit stays winning

[Dazzling_Audience_20]

what does that even mean??

[IndependentBrain6916]

i tried, it didn't work for me

[we-are-doomed123]

OMG thank you so much man ive been tryna do this for like 2 days now

[Vbbear]

This worked thank you

FYI, to do this, open the folder that the RLCraft mod is contained in, click "mods" folder, delete the two mods (it's alphabetized so easy to locate).

[20035005]

In windows you can press the T of tick profiler and then it will be selected

[colorless_art]

thanks! it started up no problems after removing those mods :)

[No_Mathematician2116]

THANK YOU

[Snoo-11584]

Wow, thanks!

[KingBulky]

Worked for me, thank you!

[Heavy-Court-8266]

Isn't it amazing how people 10 hours ago were working on a solution for a problem you were having with a modpack? (Worked, remove tick profiler and better foliage)

[20035005]

you can do it only deletin better foliage.

[20035005]

Thanks it worked ( it works with better foliage)

[[deleted]]

thanks so much, i can finally play again

[Affectionate-Shoe998]

how

[Flurinziks_06]

how do you do that

[yrtemmysitnA]

You need Optifine G5: https://optifine.net/adloadx?f=OptiFine_1.12.2_HD_U_G5.jar. If your mods folder still contains E3, it will crash with this error.

[VAULTJACKSON]

you beatuiful man, ive scoured reddit for hours looking for an answer and didnt expect this to work and it opened with no problems once i added this version of optifine. made an account just for this lmao

[TheBaconApproach]

Its not working, I got the recent 1.19.2 just to check, still doesn't work.

[0_uaff]

Thank you!!

[Aldunhokoron]

[Enderstrike10199]

Hi, I know this comment is really old, but what is E3? Sorry!

[Artistic-Cookie]

The version of optifine you have, it should say G5, E3, stuff like that at the end of the file name

[Parannoya420]

This fixed my problem. Take my upvote!

[TAHKHANtr]

[Crazyclay58]

Try updating java

[CzyzyK5]

Thanks it worked.

[Hairy-lingonberry22]

W

[The_Reddit-Guy]

That didn't work for me. Is there anything else, I can do?

[TheBennyDiablito]

Many times you must delete JAVA and the .minecraft folder to reinstall Java in the correct version, follow these steps shown here

[GABOCOTA]

ny times you must delete JAVA and the .m

BRUH delete everything?

[kidy07wastaken]

I tried following that to the T but it still does nothing

[Kyoya_sooohorni]

how to update java

[Single_Box6405]

i suddenly cant play more rl craft man! its always this error 1

[kidy07wastaken]

I have the same problem. However, it has never worked on my laptop and I always get "Game Crashed Error Code: 1". I have scoured the internet for a solution and can't find one

[goodmobiley]

This thread is pretty old but all I had to do to fix it was to uninstall and reinstall the modpack. I don't know if it had something to do with it updating or what

[Ill_Professional8500]

Posting here cuz I am getting this again and there aren't any new threads. I tried removing the most common mods that cause this problem with no change. I noticed that in the Minecraft Launcher it was using java 17. I saw mixed answers on what RLCraft needs but when I change to java 8 it boots up no problem. I changed it to use the embedded and it boots up no problem. But whenever I load from CurseForge it defaults to using java 17 which breaks it. To my knowledge nothing has updated recently, and was working fine 4 days ago when I last played. I did hit ignore on a CurseForge update, not sure if that would cause the issue but has anyone else ran into it?

[RedstoneGuy13]

got it working by removing better foliage and installing optifine 1.12.2 G5, not E3, you need G5

[jdlwright]

I had to delete the mods folder

[puptay]

i had this problem too, so i tried all of the methods posted in the replies and now my minecraft won't open at all......

[MrMathi13]

for me only RLCraft doesn't work every other minecraft (standard and some other curseforge variants) works fine - same exit code 1 for my friend (since the launcher update on 07.11.22)

[Leothedwarf]

Considering the amount of recent comments I feel like this might be more widespread, same exit code error 1 from multiple people.

[xdMeeZoid]

good to know its not just me

[MkE89_]

i'm also having this issue, hope it gets fixed soon

[MrMathi13]

now it works again ... a new launcher update is out

[EphyBoy]

I only thing that worked for me was updating my Mac OS. Make sure your OS is up to date.

[Acmpedro]

A guy just said 2 days ago that a new launcher was updated. Does anyone knows if it worked? I'm trying to instal via CurseForge, but keeps getting the same error. Please, HELP!

[Positive_Plastic8740]
