The gui-server encountered an error!

[owosoup]

Since the 0.25 beta, the gui server doesn't launch after crashes. I don't know why.

Steps to reproduce :

• Use Modrinth launcher and version 0.25 or later
• Have Kotlin and QFAPI
• Have an issue with mods during launch

Log message:

I encountered this issue as well. I tested a bit. It works in 0.25.0-beta.2, and doesnt work in 0.25.0-beta.3, 0.25.0, and 0.25.6 (and some other betas) A simple reproduction case is to load Minecraft 1.20.3 with quilted-fabric-api-8.0.0-alpha.6+0.91.6-1.20.2 and loader 0.26.0 Usually, it doesn't produce an additional crash report (Except the normal dependency resolution error log) However, stdout contains some useful information: https://mclo.gs/ut7wUzy

In other words https://github.com/QuiltMC/quilt-loader/commit/52e0ea16ef5210fc7b7ad8d47b432847a3f889df is the commit where the change happened

I've had another go, it's really strange. Sometimes, the GUI does show up, and sometimes not, in the same 26.0 version. I'll have to find how to reproduce.
