Debugger Error: "The system tried to join a drive to a directory on a joined drive."

[c424291 (Rachel M Bond)]

I just solved this today. It was not multiple AS editions, running as admin or another IDE conflicting.

The debugger message said it was trying to connect to 127.0.0.1:2323.

When I ran the following command, I saw that port 2323 was excluded and couldn’t bind.
netsh interface ipv4 show excludedportrange protocol=tcp

A stack overflow post said that Windows Hyper-V could be excluding those ports, which I had used for trialing some things with Docker a long time ago. I ran this command to disable Hyper-V.
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

After a restart, the debugger now works.
