THIS IS A REPEAT BUG REPORT, LAST TIME IT WORKED FOR A DAY, NOW ITS NOT WORKING AGAIN.
Minecraft Doesnt Want To Boot Up Any Non-Vanilla Clients (optifine, fabric, forge, etc)
This Is Not An Issue Relating To Their Specific Mod Loaders/Clients, Only MC Launcher, Launchers Like GDLauncher and Lunar Client works fine.
Only Vanilla Installations can boot up, anything else cant boot up and it just crashes instantly
Bugged Versions : 1.18.1 1.18 1.17.1 1.17 1.16.5 1.16.4 (not sure about any versions below, down to 1.8.9)
(the bug also happens on win11 according to my friend)
(Currently using the old launcher, not the Microsoft store one)
The Java Runtime Enviroment Has Been Reset To Default
-Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

Sorry for taking 3 months, I've resorted to other launchers, but now those dont work anymore, the official launcher still does not work.
