Unfortunately, [App] has stopped working

[AC Question]

Okay so I had this tablet from a specific network for 1 year now. One day something poped up "Unfortunately, Server has stopped" and the only button available is and when I press it, it pops again. When I press it again, it pops again, endless cycle. I already did a hard reset. If I open the tablet, it already pops. I can't press anything because that keeps popping. Need help.

Welcome to Android Central! Which tablet? By "hard reset," do you mean a factory reset? Does this happen in Safe Mode as well?
