I created new Maui project and I cannot work due to error. After start debugging, stop, and try to run again.

System.UnauthorizedAccessException: Access to the path 'C:\Users\xxx\source\repos\MauiSygic\obj\Debug\net9.0-android\android\assets\arm64-v8a\Mauixxx.dll' is denied.

Sometimes we see this when the path is too long. If you move your project to a shorter path, does it build? Does this happen with every project or just this one? Does it happen every build? Thanks!

Why do we ask for more info?

@dellis1972 maybe another thing to be resolved by https://github.com/dotnet/android/pull/9423?

[dellis1972]

Possibly yes :D

[dellis1972]

More likely resolved by https://github.com/dotnet/android-tools/pull/245 and https://github.com/dotnet/android/pull/9423
