Hello we have an issue, which is more than annoying. Ever since we upgraded to BIG SUR our IOS App fails to load in ANY Simulator IOS version below 14.4. We are showing a very small video on app start which uses the AVPlayer which when commented out lets the app proceed, but as soon as the AVPlayer is attempting to play something the App comes to a stand still

In oder to actually test our app I needed to install Catalina on another partition and run it on Catalina instead. By the looks this issue is not new and has been reported over a year ago and there is still no fix.
NOTE: The app works fine on real devices.
