Hello, Retrobat games/roms wont boot up anymore?

Hello everyone, hope all is well. I had a buddy of mines build me a Retrobat build with with almost every emulator on it. Everything was working fine until it randomly stopped playing games. Everything seems to be working fine in the menu, but once i press on any game it loads up quickly to a black screen like its loading and then goes back to the menu/frontend. This is the second time it has happened and supposedly its due to Windows security preventing the games from playing, but i already added Exclusions through Windows security to my drive where everything is located in. Im barely getting to know the program myself, since my buddy did all the work. He is currently out of town and wont be able to ask him for help unfortunately. Any help in advance would be appreciated. Thanks again and have a great day!

Does anyone have a fix or any tips on how to fix this? It was playing just fine yesterday and suddenly stopped working.
