Help with Smart App Control issues regarding .NET Runtime Optimization Service and Windows Subsystem for Linux (WSL)

I am having huge problems with the new Smart App Control feature in Windows 11 Home (windows build 22621).

After activating some Windows Features, Smart App started popping up with warnings that the .NET Runtime Optimization Service has been blocked and has stopped it from loading. Also DLLs that I think are almost certainly signed by Microsoft (mscorlib.dll, System.dll, System.Net.dll, etc) are all getting blocked and keeps giving these annoying notifications until I switched it off.

It is also blocking WSL, an app that is offered by Microsoft in their app store is being blocked.



How do I configure Smart App Control to run .NET Runtime Optimization Service and WSL properly?

 

.NET Runtime Optimization Service

This showed up on my Windows 10 after a mandatory update by Microsoft. Now a perfectly good computer is acting up as usual after updates.
