I would love to know how to troubleshoot this problem - seems like a driver update from Sonic Radar or realtek drivers via Microsoft store (UWP drivers)
After uninstalling the latest updates of Sonic Radar and Studio - I can confirm the copy/paste problem is gone. I updated via the Windows Store (their UWP driver) - so I decided to uninstall the 2 programs.
Watch out before you update those 2 programs via Windows Store
