Visual Studio Debugging issue with 90.0.818.8

Hello, 

after update to Edge 90.0.818.8 yesterday, we are having big trouble with Debugging MVC Applications in Visual studio using Microsoft Edge. 

First time startup works fine and Edge is opening and displays everything. When stop debugging and restart afterwards, the following message appears in Visual studio: 

The only workaround at the moment is to open the Task manager each time you stop and want to restart debugging and kill all msedge.exe processes manually (and there are a lot even though all Edge windows have been closed). 

Thanks! Jan
