Upload to build service is stuck while trying to export the game

Hello, I am trying to export a game onto android. Before when i exported games, i had no problem with the upload to build service. But now, for some reason, no matter which project i try and upload the build service fills the bar completely yet doesn’t work after that. I have no idea why this happens, the game is not large (it’s only 480 KB). I do not know how to fix this, any help is appreciated
