Module loading error

I'm having an issue loading the Ultramodern 5 Redux module into my game on test build 4.1.0. The module loads perfectly fine on public build 4.0.10
I keep getting this error:
4/23/2021 1:27:03 AM] MEASURE: MODULE LOAD - 0.266224 - Ultramodern 5 REDUX (5e)
[4/23/2021 1:27:10 AM] [ERROR] Process Data File (Ultramodern 5 REDUX (5e)): '.', hexadecimal value 0x00, is an invalid character. Line 2, position 1.

Already tried:
Uninstalling and reinstalling Fantasy Grounds Unity
Creating a new campaign and copying the campaign.xml to the original campaign
I've even tried just starting a new campaign all together

Any help would be appreciated.

There was a new update pushed to the Test channel last week in preparation for release. I've rolled it back to the Live version for now; and we'll notify the DLC developer.

Regards,
