CRITICAL Total-Lockup-Freeze, caused by 'Use Device WinRT MIDI' (Cubase 15.0.1)

The problem for me, is when I have WinRT MIDI on, it sorts the ports properly in the Track MIDI Input/Output selection menu - but - with it on, I also have this terrible freeze crash happening.

With WinRT MIDI off, the Track MIDI In/Out ports are randomly out of order.

I have a feeling it happened when I engaged ‘Use New Names’ in Windows MIDI services… not 100% sure on that though.

I have a thread for this discussion as it’s unrelated to this thread:
