MS Photos Not Working

[RBC]

Unable to trim videos using MS Photos in Windows 10. Result of recent attempts: (a) app reaches roughly 90% complete, then never finishes, or (b) app abruptly terminates. Tried repairing and resetting the app, and restarted the computer.

App used to work okay, with only occasional failures, but trim function is no longer usable.

Suggestions?

Maybe you have a corrupted file. To check & repair, you can run the System File Checker from a command prompt: 'sfc /scannow'
