Hi there! I’ve been trying to package a preview build of my game to send to some friends to make sure the online front of things are working smoothly for a much bigger test down the road, and yet I can’t seen to move from step one… Which is packaging. For some reason, no matter what I try, I always end up with “Error: Launch Failed! Unknown Error” and I have already tried copying the marketplace plugins into the main project folder and it just told me in packaging that the copied plugins were just duplicates and caused more errors. Here is the full log that I get when I try to package the game:

If anyone could point me in the right direction and maybe give me some ideas on where to look or what to do that would be amazing!
