Studios test being extremely slow

When I’m using studios normally, studios runs fine. When ever I test my game, didn’t do this before the update, it lags an insane amount. I have tried reinstalling studios, my computer has been restarted multiple times, I’ve turned the graphics down all the way. Nothing. It’s not my code. I’m in a team create, and everyone else’s test work just fine. But, I can’t even test my game, testing is just too laggy. It’s quicker to publish the game then test.

If anyone knows of a fix please let me know.
