This crash occurs while loading in 1.20.1 latest patch. It is not a mod incompatibility

This has been fixed as of the most recent patch

I also crash on start up, it's when I use the latest Version of NatureSpirit, the error I get is as followed.

yeah same error. Do you have a rudimentary fix btw?

sorry for the late response, I just downgraded by a version, it works fine on the pervious release, just the latest 1.20.1 release crashes on startup, the crash was tested with the latest 1.20.1 NaturesSpirit release, and no other mods, so it's a bug with the latest release of NaturesSpirit for 1.20.1

thanks, no worries. I’ll update the post with your info
