I have just upgraded my Photoshop Elements to 2021 version on Windows 10 PC and now whenever I try to open the Organiser my whole computer freezes and the only way I can get out of it is to shut the whole computer down using the on/off button. I am unable to use Task Manager to close any windows. The whole machine becomes totally unresponsive. I have tried to rest the preferences and this worked once and then it crashed again. I have also uninstalled and reinstalled the software and still the same problem.
Crash or freeze, Organizer, Problem or error, Windows
Try pressing the Shift key while opening the Organizer. This will open the Manage Catalogs dialog. Create a new blank catalog and see if you can open the Organizer with it. If the Organizer opens, you can then try to repair and optimize your existing catalog to see if that will allow you to open it. Once the Organizer opens, you might also want to turn off all Media Analysis in the Edit>Preferences>Media Analysis dialog. Then see if your existing catalog will open.
How large is your catalog and do you have many video files?
