Crash during startup with FrozenLib (for e.g. Wilder Wild, etc.) on 1.20.5/6

[pnk2u]

So since 1.20.5/1.20.6 (this issue did not occur in 1.20.4) the game would not start-up with both Wilder Wild and Lighty installed, displaying this crash message in the launcher:

The game crashed whilst initializing game Error: java.lang.RuntimeException: Could not execute entrypoint stage 'client' due to errors, provided by 'lighty'!

The crash report then reads as follows:

Description: Initializing game

java.lang.RuntimeException: Could not execute entrypoint stage 'client' due to errors, provided by 'lighty'!

Last time I didn't realize/check what the problem was, but after this recent update I checked again and saw that FrozenLib was involved in the problem. So I figured, why not just try not loading the relevant Mixin and that absolutely works. So I'll tell you what I did because I while I was able to fix this problem for myself I have barely any understanding of why and how: I removed the "ScreenMixin" from the file called frozenlib.menu.mixins.json(linked to the file in their repo) and replaced the updated file within the jar instead of recompiling because I'm lazy. :D

Thank you for reporting this issue and for narrowing the mixin down! Highly appreciated!

I've had a look at it and I think I know a way to fix it, but I still have to try it out. I'll keep you updated here.

If I am correct, I should be able to fix this issue fairly quickly, but because of university stuff it might take me a week or so to actually get around to fixing it and to release it. Hope you understand!

I'm glad to hear that that helped.

Ah, nice, thanks a lot.

And no worries at all, that's of course absolutely understandable, and regarding me, I already have a band-aid fix that will last me until then. ^^

[andi-makes]

Fixed in v3.0.0-beta.3+1.20.6, let me know if it also works on your side and we can close this issue :)

Just tried it and yes, it works for me, too. Thank you! (:
