So, I tried the following:
- Save the project locally, reload it from the local drive and export it.
- download the project from the export manager instead of the download button.
- I turned off Windows Defender, in the custom settings and in the advanced settings.
None of that worked.
Then, the best part, I loaded the game project on ANOTHER computer, and exported it from that computer, then ran it on that computer, and as incredible as it sounds, it was STILL not working!
As a final try, I deleted the Steamworks plugin and exported, and with it removed, it WORKED!
So, as stupid as it sounds, it seems to be the Steamworks plugin is causing this bug.
I recently had more problems with Steamworks plugin (see here), so at least for me it seems to not be usable in its current state
Ashley . Unless something is wrong with my computer or the way it is setup, or I don't know what.
If you need more information about this problem, I'd be happy to help. I can imagine I'm not the only person in the world to run into this kind of problems.
