I get a crash whenever I add CEM in with this mod, but as soon as I remove CEM it stops throwing a unhandled solver error and boots minecraft perfectly fine.

Not sure how to proceed with diagnosing this, but here is my crashlog:
crash-2023-05-20_14.06.43.8443-quilt_loader.txt

Cem is listed as incompatible and thus they both cannot load together, i guess quilt crashes in these cases which sounds like a weird way to handle it

Fabric will give you a warning screen and explain the issue

Hm. Alrighty. Thank you.

For some reason the fork I'm using of CEM said that ETF would "expand the capabilities of CEM" and never said the two were incompatible. Guess I should've done a tiny bit more of research.

Thanks for clarifying though!

ETF is compatible with cem, but EMF is not, they are two different mods

Delete CEM, you don't need it when using EMF.
