This dialog shows up during initialization of the game, which up to this point is windowed on my desktop and completely white. At this point, the game completely hangs. It is also important to note that closing this dialog closes my output log window and my Minecraft launcher window.

Speaking of output logs, the last line before errors pop up is:
Mixin Conflict Helper | Render thread | Forking JVM to display Swing GUI (bypass LWJGL)!
Here are the errors in question.
latest.log can be found here.

This is a modded Minecraft 1.19.2 environment using Fabric Loader 0.14.10
All mods are up to date (except MemoryLeakFix for a dependency issue).

I will cross-post this issue to Lithium as well.

Oh my goodness, silly me..

It has come to my attention that the version of Lithium I was using (lithium-fabric-mc1.19.2-0.8.3) is outdated. Sincerest apologies for the inconvenience.
