Hi Mark
I regularly run both instances (V13 & V14) on my Win 10 machine. No issues here. I would look for a Windows issue. Have you made any changes, added new software, updates, others….. ? There may lie your problem.
A regular clean-up of your PC is always recommended. Windows is known for accumulating ”crap” as time passes. If that fails, do a clean uninstall of your VPro‘s and re-install. If that also fails, after you have tried everything else, back-up everything and do a clean install of your OS. (had to do that once with V7 way back…)
Cheers !
