Ordinary jpegs DXO 9 now won't open

[unchdxoly ((PL9, macOS M1 Pro))]

If I were you I’d try these troubleshooting steps:

1. Restart your computer (I’m assuming you’ve already done this), and if that doesn’t work, then:
2. With PhotoLab closed, delete your PhotoLab database (first back it up – I’m not sure where to do this on Windows, but on Mac it’s File → Project Database → Create a Backup), and if that doesn’t work, then:
3. Uninstall PhotoLab entirely, and then reinstall PhotoLab, either version that you prefer to use right now
