Photoshop Elements editor will not open

I have used PS elements (currently on 2020) for several years - Recently, the loading screen opens, the organiser opens from that, but the Editor will not open.  I have tried opening as Administrator, Running the “.exe” file direct, uninstalling and re-installing, then all of the above again, but still not working (Windows 11) 

I don’t need all the new stuff on 2025, and am tempted to ditch it completely due to frustration - I have been trying workarounds for several hours.
