I cannot see anything obvious. Can you try to only install fabric and ambientsounds and see if it works. If yes add back in your installed mods to see which mod is causing the issue,

Same issue with me, i've done the this exactly (removing all my mods except ambientsounds, CreativeCore and fabric) same issue. However, this only happens when joining servers, singleplayer does fine.

I have released a potential fix. Can you download the newest version of AmbientSounds and see if the issue has been fixed?

seems to have worked, no longer crashing when logging into servers, I can try to get it to happen again and send bug reports or something. I'll let you know.

Ok, I will close the issue for now. If it occurs again post the necessary information here and I will reopen the issue.
