Mod version: Projectiles-1.0.0-1.19.2-Forge
Forge 43.4.0

When I first open minecraft every day the mod causes the crash seen in the screenshot, the second time I launch the game it opens completely fine, after that if I add or remove a mod and restart it will crash again with the same message.

I've attached the debug file, the crash report and the crash screenshot.

If you have any questions please ask. Thank you.

Update: If I use Forge 43.4.2 it crashes every single time.

Looked at the logs i tried forge 43.4.0 & 43.4.2 both loaded I thought maybe it was something to do with fastutils and the only mod mixing into it was "majruszlibrary" but I tried that mod with it and it still worked my only other idea is prism launcher is doing something invasive to forge or there is a mod that is messing with event registration. do you happen to have a modpack link I can download, (im working on a full rewrite of the mod anyways :) )

Although I don't know if it's not a launcher issue, I have tried the mod with the same "modpack" on curseforge launcher and on an Exaroton server, and it resulted in the same crash, on the server the crash did not fix itself on the second try like it had for the Prism and Curseforge launchers, so the server wouldn't open. I don't have a modpack because there are paid mods in it, so I'm sorry I'm not able to help there, although I'm glad to hear you're working on a rewrite as I really like the mod :D

Crash report on the Forge 43.4.2 server:
crash-2024-07-09_14.27.01-fml.txt
Crash report of the curseforge launcher crash (forge 43.3.8):
crashprojectiles.txt

so I tested your modpack from the crash report I downloaded every mod using the curseforge launcher and there was only like 5 I couldn't find and it loaded just fine... I'm not sure what mod I'm missing that is causing issues with projectiles but if I cant download it I cant find a fix.
