'Slight' Gui Modifications and Rainbowify seem to be incompatible.

The game crashes before the main window would have a chance to open.
I'm running 1.17.1 from multimc, everything is latest.
Removing either mod fixes the issue. I have sodium and indium installed.

Here's the full crash report.

I've reported this to both mods' issue tracker, and I'll update both issues with info from the other.

seems like it's an issue on Rainbowify's side, I'll close this if that's actually the case once it's fixed
