Hello.
This issue usually happens when the Photos app loses its permission to access external devices (SD cards), even if the settings appear to be enabled.
Please check the following:
- Reset the Photos app permissions
Go to: Settings > Privacy & security > App permissions > Pictures
Make sure Microsoft Photos = Allowed.
Then also check: Settings > Privacy & security > App permissions > File system
Turn Microsoft Photos = On.
Then also check: Settings > Privacy & security > App permissions > Automatic file downloads and make sure it is Allowed.
- Reset the Photos app
Go to: Settings > Apps > Installed apps > Microsoft Photos > Advanced options Select Repair, then Reset.
- Try importing again from the Photos app
Open Photos → Import → From a connected device.
