This is driving me mad!

Hi all,

I posted something similar to this issue a while ago but have not solved the problem, so trying again.

For some strange reason I'll be working on an image in Photoshop (latest version), or I'll open Photoshop and my workspace has changed, my plugin panels are gone, plugins are not listed in the plugins menu. Hitting reset workspace doesn't work. If I then connect to Adobe cloud and it opens I check that my plugins/panels are installed and then go back to Photoshop. Then, here's the mystery, all of a sudden my panels/plugins are open and bunched together on the left side of the interface. If I then click reset workspace everything is good. Resetting Photoshop preferences did work once, but I'm at a loss to understand what's going on here. My PC is working fine with everything else, no malware/viruses etc. Not sure if one of my plugin panels is to blame. Any help/suggestions welcomed. Thank you in advance.
