I’ve been working on this project for a couple of months now, thus the older version. And thus far I was able to solve every packaging issue, because the log provided a specific error I could fix. However, now the log only produces an unknown cook failure, without any other specific errors.
Maybe I am overlooking something, so I hope someone out there can spot the problem in the log.
I also created a new clean sample project, where packaging worked fine. Resetting the project settings and caches also didn’t help.
