Additional context
Also posted on lootbag's github here: Malorolam/LootBags#203

just FYI, I'm using the jar you posted there and it did resolve the crash, even when I re-enabled all my loot scripts. I'll continue using and see if I run into any other issues to help test. Any other features you want me to test on this experimental jar? Thanks for looking into this

I was actually referring to a test JAR I posted in my Discord that additionally fixes #63, but it's good to know the #62 test fix JAR works.

This happens with no loot scripts enabled.

There are definitely scripts enabled, the method that's causing the crash is never called in LootTweaker itself.

The issue itself has the same root cause as #62. It's already fixed in dev, I'm just waiting on people to test a test JAR before I release. I've had too many major issues reported right after release lately.
The crash is caused by faulty error handling, so it won't happen if there aren't any errors to report. You've got an entry name wrong in whatever script is still enabled.
