Packaging Error in 4.25

Hello,

I tried upgrading a very clean BP project from 4.24 to 4.25 - It build with 0 warnings / 0 errors in 4.24 but in 4.25 it throws these callstack errors. I tried already a lot to debug, but couldn’t figure out what caused it.

Here’s a screenshot of the log: callstack2 — ImgBB (directly uploading images / attachments was not working for any reason)

Please help!
