Windows 10: once trimmed, video cannot be saved

MP4 video files that I save to the desktop can be played using different apps. But when I trim this video file using movies/ tv app/photos app, it freezes with the message This file isn’t playable. That might be because the file type is unsupported, the file extension is incorrect, or the file is corrupt. Help me to sort it out please. The error code is 0xc10100be

:)

 

trim video

in the photos app, drag the white circle from the left side to trim off the beginning of the video, you should see the video change as you do it.

Drag the white circle from the right side to trim off the ending.

it will not allow you to trim the video to less than 1 second

you can play the video at any time to see what remains after trimming.

when you are happy with the result click save a copy in the top right of the screen or right click anywhere and select save a copy, it will be saved in the original location with trim added to the filename.

 

trim video

How do I trim sections from a video in Windows 10? If it's to be trimmed in Photos, I'm unclear how to properly position the bottom brown line (left and right sides) and white circle....and whether/how I need to save sections to the storyboard...and
then how to save all sections of storyboard into 1 video. Very frustrating trying to find clear-cut instructions.
