Failed to open descriptor file

Hello

I have just packaged my game using project launcher. The apk file seems to work on my android smartphone, but it doesn’t on all the other ones. It works on my phone, probably because i have launched my project on it before when connected to the computer using USB.

Error:

I’m having the same problem - I package (shipping) my simple room game, and then try to run it and get the exact same thing.

I get this message whenever I package for shipping. It happens for windows 64 and 32 as well. If you find anything out let us know!

I would also love to see if there is an answer to this. I am stuck for over a week on this error.
