My game compile's but doesn't run?

So as usual I was in a coding session, and I decided to playtest but then it would compile but never run. I found an old forum from steam about a setting I can change but it's not there anymore.
Then I tried relaunching Game maker still doesn't work, and then finally I restarted my pc but it still has the same issue. I am trying to not have to re-install. So is there anyone who may know a currently working fix?
