I was getting Unauthorized Access and Access is denied in IIS Express or Development Web Server all of a sudden. Turns out it was because my source control made the directory read only and this seemed to be causing the problem.
I also seemed to have to restart IIS for it to start working again.
I had some problems with the Logitech MX Master 3S Mouse with an M1 MacBook Pro, but I had better luck with a Logitech G502 X Mouse
