I'm not really sure what's going wrong here, I was trying to update mods in my modpack today and ran into this issue. My best guess is something regarding EMF's config got changed but I really can't tell.

Here's the crash report and log:

Also, I went to join the Discord since usually that's the first place I check to see if an issue is known, but the link appears to be broken/expired.
