An excerpt from the crash log:

- Mod 'Colormatic' (colormatic) 3.1.2+mc.1.19 recommends any version between 3.0.0 (inclusive) and 4- (exclusive) of mod 'Mod Menu' (modmenu), but only the wrong version is present: 4.0.0!

I don't know how Colormatic works internally, but my best guess is that compatibility might be restored with a simple dependency version bump.

Now that I test it without Colormatic, it probably is. Thanks for your time, though.

Cannot confirm, runs fine for me.

Correction: Shows up, but it's recommended, so will run fine. Your crash was most likely unrelated.
