Trouble with win11 midi ports

Hi there,
I bought a new mini-PC with win11. It worked fine since yesterday. But now I’ve got trouble with my midi ports, all of them are disconnected since the last update. I guess it’s a security problem because I found alle devices on the device-manager and they are all correct recognized and connected. Does anybody has the same issue? How can I fix this?
thanx in advance

I found out, that the devices are not connected if I want to use the pc vie RDP. Does anybody know a solution?

RDP has some issues re multimedia ports, as has been discussed here in the forum:

I use alternative means to remote-control my Cantabile PC - no such issues with USB ports so far. My current favorite is RustDesk - free and open source and works nicely.
