Unity built my project, but won't run it

The editor version is 2020.1.0a8 alpha Maybe I should build the game in a more stable editor version? The console shows a few errors, but they do not affect the game at all when I test it out in PlayMode. Maybe these errors have a more drastic effect on the built .exe? Do you think that the two reasons I listed could be the issue? Do you have any other idea as to why the build won't work? Thanks!
