I'm very new to deployment on an iOS device, but I have a MAUI app I'm trying to test in a simulator. Unfortunately, every time I try to launch I get a black screen and the console just shows a ton of warnings in UIKitCore for my process that say:

"Rendering a view (0x7fb5f6a76f0, UIWindow) that is not in a visible window is not supported (no context)"

I was able to get a completely fresh project deploying and running on my simulator, so it has to be something in my app, but I have no idea where to start. Any thoughts would be great!

The log message doesn't seem relevant to precluding your launch (it has to do with trying to take a snapshot in a specific circumstance). Do you have a crash report or an other hard error?

Thanks for the response. There's nothing in the crash reports for when it black screens, just showing some earlier ones when I had an actual error.

Today, that message is not appearing in the errors and faults, I'm not getting anything negative from the processes. I captured everything with my app name here and tried to investigate each of the issues, but not getting very far. The "could not find maui framework!" is interesting but seems to be in the accessibility settings, and doesn't appear every time it fails. I can also track down the messages that aren't labeled as errors or faults, but there's many many more.
