Cubase stops responding to mouse clicks

System Specs:
Cubase 13.0.30; Windows 11 Pro 23H2; Intel i7-13700K @ 5.1 Ghz, 64 GB RAM; Logitech MX Ergo

I’ve just experienced a weird situation where Cubase stops responding to mouse clicks mid-session, but still responds to keyboard shortcuts and an external control surface. I’ve confirmed that the mouse still operates normally in Windows and other software , just not in the Cubase UI.

This issue occured in a multitrack project after rendering a stereo audio clip into L & R mono clips and had just inserted the stock MonoDelay plugin on the R track. When the delay plugin opened, the mouse stopped responding. I tried recreating the issue by going through the same routine, but Cubase responded normally.

Can anyone else confirm they’ve experienced this? Would like to know if it’s just me or not!


I’m experiencing it too. So far about two or three times only so it’s hard to tell what can cause this.
I have this issue on windows 11.
