Xcode 11 simulator 12.4 won't boot

Hello,


Ever since I installed Xcode 11.3, I have had trouble with the 12.4 iPhone simulators. They will run, but all I get is a blank screen. Is anyone else having this problem?


Note that I have multiple versions of Xcode installed on my machine. Currentlly 11.3, 11.1 and 10.3. I have them in different folders under /Applications, except for the 11.3 version which is the default /Applications/Xcode.app. The other two are in /Applications/Xcode_11.1/Xcode.app, and /Applications/Xcode_10.3/Xcode.app.


Also xcode-select is set to /Applications/Xcode.app/Contents/Developer


Any thoughts as to how to fix this?
