Editing, Freeze or hang, User interface or workspaces
1) Make sure that G-Sync is OFF in NVidia control panel
2) Try to reset workspace: Window > Workspaces > Reset to saved layout
3) Try to turn off Hardware accelerated DECoding in Preferences > Media... It's recommended to clean media cache each time you change that settings, or after any app update. Close PP and manually clean media cache (goto %USERPROFILE%\AppData\Roaming\Adobe\Common and clean/delete foldersMedia Cache, Media Cache Files, PTX, Peak Files)
