1.20.1 [1.20.1] Modpack crashing on startup - Mod not loading correctly

[SeniorDee]

I tried adding the Create (6.0.4) mod to my modpack which causes it to crash before it finishes loading. I tried removing the mod Cold Sweat because the error said it failed to load due to something in Create but when I removed it, it kept crashing; and I also tried downgrading Create, but nothing helped.
I assume there's an incompatible mod that's causing Create to not load correctly, but I can't find it.

launcher_log.txt: https://mclo.gs/kn5Qkk2
debug.log: https://mclo.gs/zIKoAaB
crash report: https://mclo.gs/j86C10Y

The part of debug.log that I think is the crash (after Create mod already loaded incorrectly):

Update ColdSweat to the latest build:

I did that, and then it crashed again, but this time it said something about ComputerCraft; so I disabled that mod and now it works. Thanks for the help!

Same here, I faced it too.
