Solution exception:Operation not permitted on IsolatedStorageFileStream

Huh?

When I opened a Gh definition with a component which I developed in VS2022 (which was tested by executing debug from VS2022 == ok), the component has a problem with the following error message:

What can be the reason for this error?

Neither my component (C#) code nor the GH definition itself open any files, and still I get this error.
