I'm making my own custom modpack using CurseForge, pretty sure most of the mods are 1.20.1 so I'm not sure what the problem is.

It crashes on this every time:

Yes both of those are installed, I believe all of the dependencies are apart of the modpack.

Use a pre-configured modpack as working base - then add some mods

So I have disabled the dependency mods, Forge loads almost to entering the menu with majority of the mods loaded and crashes.

Here is what it says now: https://pastebin.com/mPMDAcWq
 

 

There are issues with createbigcannons and artifacts - remove these

If this works, check for other builds of these mods

Okay update to this, I've figured out you can use older versions of the dependency mods to fix crashes like this. Thanks for the help.
