Help panning issues

So Im having panning issues from cubase VST’s. They start off fine then for a unknown reason they suddenly they pann far right, I’ve included a pic that shows the extreme. I have to drag the panning cursor far left to bring it centre. Any ideas? checked all issues in standard settings. Like I said its fine at first. Cubase 12 pro windows 11.

Do you have any MIDI Remote, Generic Remote or Mackie Control devices configured? If not sure, please double check.

This could be all or nothing…
