Crashes immediately after pressing "play" in the launcher - no mojang screen.
No other mods added.
No entry in log.
No crash-report created.
Simply Exit Code -1 in the Launcher.
Forge without the mod starts fine

I have tested the version with Forge 48.0.34 and it worked there.
I'll take a look at it tomorrow after work and try to figure out what broke.

Thanks for the report, I found the issue and am currently waiting for Curseforge to approve it, it's version 1.16.4 for 1.20.2
