I haven't change the code before and after the upgrade
However, it can run in Debug, but cannot run in Release, during the release compilation process, the compiler did not report any errors, but the compiled program did indeed crash directly, but Debug can run normally.
Before I upgraded the Visual Studio to the Version 17.8.0 both Debug and Release can run normally.
Now I upgrade the Visual Studio to the Version 17.8.1 the problem still not solved.
My .Net Version Is .Net 7.0 and I never change it.

Did you clean up the project's bin and obj folders and reopen this project after upgrading VS?
If the problem persists, it is recommended that you report the problem to Visual Studio feedback for VS compilation-related problems.
Yes,I have clean up bin and obj folders, and problem still remains

I have exactly the same problem. After upgrade to 17.8, release build of my .NET 7 MAUI app crashing at startup.
My solution is upgrade to the .NET 8.0, but... well i never think its a solution for this problem
However, when I change my .NET Version To The .NET 8.0, the problem solved, but I don't know why
