Hello @twertown . can you reset your preferences in Photoshop
by Press and hold Ctrl+Alt+CShift (Windows) or Cmd+Option+Shift (Mac OS) when launching Photoshop. You will be prompted to delete the current settings.
if it doesn't work .. i think you have to reinstall the program due to " the app was moved, or some files have been moved/deleted.
The 3D workspace is not where it should be in the Photoshop Required/Workspaces folder. "
