Description

PlatformNotSupportedException prevents any module from being imported.

Steps to Reproduce

1. Target Android .Net 6 (MAUI)
2. var aPythonEngine = Python.CreateEngine();
3. aPythonEngine.Execute("import foobar");

Expected behavior: No error if "foobar" is in the search path and valid; "No module named 'foobar'" if it does not exist

Actual behavior: Throwing System.PlatformNotSupportedException: Operation is not supported on this platform. at IronPython.Modules.PythonNT.stat(String path, IDictionary2 kwargs) at ...

Workaround: Hooking OperatingSystem.IsOSPlatform(string) and let it return true when the argument is "Linux", then the issue magically disappears. Everything else seem to work fine with android (As long as you redirected your stdin).
