Project Won't Package

Forgive me if this is unrelated, however, I didn’t see a place appropriate for my issue.
Today I tried packaging my game, and I almost immediately get an error that says “Unknown Error”, with nothing helpful in the log to state why it may have been unsuccessful. I’ve tried everything I could think of, and with no luck. I don’t really know what to do, some help would really be appreciated, this is the second project of mine that this has happened to.

If you can’t find the answer with the log then nobody here has a chance of figuring out the issue without even THAT. Post the log from a failed package build here.

Generally the answer IS in the log, even when it seems like a dead end. It might say “Unknown Error” but scroll far enough back up the log and check the errors and you’ll find the cause more often than not.
