Can't drag and drop items now

HI everybody
For some reason now in Zorin 15.2 I can no longer drag and drop items. I have done a search and tried doing things like enabling/disabling ‘new views’ under ‘experimental’ with no luck.

For some reason this was working, but overnight it decided not to. Anybody able to give me some tips about how to fix this? I use it quite a bit so this is a bit annoying.

Thank you for any help here.
