Quilt 1.20 Crashed with only QFAPI mod

When launching the game, it successfully opens the Minecraft loading screen (the mojang studios loading). It loads up until around 90% and crashed. I only used the Quilted Fabric API (QFAPI) / Quilt Standard Libraries (QSL) mod.

Here is the crash report:

Could you, please, try updating to Quilt Loader 0.19.1? This is a very strange error.

Also highly recommend updating to 1.20.1 along with QSL.

Hey, I tried updating to Quilt 0.19.1 for 1.20.1 along with the QSL. It still crashed

Now it looks like Quilt jar is corrupted, as it says it’s empty… What launcher are you using?

I use the Tlauncher Legacy, I only have this problem with the new version (1.20 and 1.20.1), I have no issue with the previous versions (below 1.19.4)

Ah, unfortunately, we are unable to provide support for cracked launchers for this reason, among other things. Sorry!
