Can't swap to monitor mode.

I’ve spent hours searching and can’t find anything to solve my problem so I’m posting here. I found this saying to “Try setting your keyboard to EN-US, remove other keyboards, and restart the application” But everything is already correctly set. I’ve also tried pressing EVERY key as well as trying to use a controller but nothing it working and I am unable to use the app.

Okay I figured it out, the map I was trying to load had too much stuff on it, seems if you go too far beyond the limit of placing things it just puts your in Spartan mode and won’t let you switch. Guess I’m good, though if anyone has a fix for that I’d like to hear it.
