Could you please send the full log? I cannot seem to recreate this issue with just Piglin Proliferation and Neurina installed.

This also might be a problem with your java version being borked, though I only encountered previous issues of this being a cause via a quick google search. I'd still try to find a way to reinstall your launcher's java if this is the case.
