How do I fix: sorry photos cant open the file because the format is currently unsupported or the file is corrupted (trying to import pictures from my camera - not RAW on to my new laptop)

I am trying to import pictures from my camera - (not RAW) on to my new laptop, Windows 11. Getting the error message 'sorry photos can't open the file because the format is currently unsupported or the file is corrupted'. Have tried 'Reset' and 'Repair' on the Settings tab under Apps - Photos - Advanced Options but neither worked. Hesitant to try anything out of S mode given I then can't get back in to S mode if it doesn't work. Can anyone help?

 

Why Unsupported format files are opening with chinese format in notepad

Old Mac formatted photo files need to be opened on my PC.

The files themselves are jpeg, tiff, or psd, but the external drive itself was formatted for Mac. When I set up the external drive it asked whether
to format for Mac or PC. When I attach the External Drive to my PC, the icons for the files showed up on the screen but when I click to open the file
is "not readable". When I took it to a shop, the guy saw the icons on the PC screen and assumed it was ok I guess.
