Hello,
I can't start a game and the logs led me here.

This is not the right repo for this....
But, since we are here now, try it without optifine. It is likely the problem.

[tajemniktv]

Oh, the at cpw.mods.modlauncher misled me.
Still the same problem without Optifine

[FinnT730]

Can you also give the log without optifine?

[tajemniktv]

Yea, sure :)

So, I should have seen this sooner....
Can you try it with Java 8? Minecraft is build for java 8, and you are using java 11

[tajemniktv]

Default Java (the one that came with minecraft)

Remove or update performant, You're currently loading a 1.12.2 version which aside from it being for a completely different Minecraft version also has Mixin compiled in which is causing class conflicts with MixinBootstrap which is why you're getting an IllegalAccessError.

[FinnT730]

Mate, this is 1.15
Look better, it is at the top of both files. I already asked in discord if something changes or not.

[tajemniktv]

Oh my... I haven't seen that I've downloaded Performant for 1.12
Thank You so much, if not You, I'd still be stuck...

[FinnT730]

Wait.... What is performant???

https://www.curseforge.com/minecraft/mc-mods/performant

small,lightweight mod project which hugely improves TPS and blocklag.

No problem, Make sure to close this issue if it's been solved.

Finn, If you read the end of Line 7 in the debug.log it shows ModLauncher loading performant-1.12.2-1.10.jar

[FinnT730]

Yeah... Read it wrong, thanks for noticing... But hard to fix things when you are on the ohone haha
