ESPHome stopped and won't restart

Just recently the ESPHome Addon has stopped working but the ESP32s are still working and temperature readings are coming in to home Assistant as normal. If I click on the sidebar it says ‘This addon is not running, would you like to start it?’. If I say ‘Yes’ I get ‘Error starting the addon’.
IF I try to uninstall the ESPHome addon I get this:

I have tried manually pulling the image as advised in another post but that doesn’t work either:

Should I try to delete the file that the error message says already exists to allow the new version to be created?
Anyone suggestions?
