Sorry for the inconvenience.
First of all, please try creating a new catalog and see if gets created.
To create a new catalog, perform following steps:
1. While launching Organizer, keep Shift key pressed
2. Catalog Manager dialog will pop up
3. Click on New to create a new catalog
If you are able to create a new catalog without Organizer crashing, -
4. Go to Edit > Preferences > Files
5. Uncheck the option to automatically generate thumbnails of video files.
6. Once done so, switch back to your older catalog from File > Manage Catalogs
If issue still persists, I would request you to please share Event Viewer logs. Follow the steps mentioned in Photoshop Elements Editor Help | How to Find Crash Logs on Windows to get those logs
Thanks,
Anwesha
