Hello,
Could someone test and verify this is an issue or if it’s just me. I am doing some automation tests with TeamCity, Horde, and UBA. I made a blank project in UE 5.4.4 and tried to package a development build and it bombs with a bunch of Fab plugin errors. If I disable the Fab plugin it builds fine.
