Photos app - trim a video - error

Hello,
I am trying to use the built-in Windows 10 Photos app to trim a video.
I have the video playing in the Photos app and click "Trim Video" at the top.
I move the sliders to select the start and end points.
I click "Save a copy" at top-right.
The app says "It looks as though you don't have permissions to save changes to this file. Try saving a copy instead."
Having just clicked "Save a copy", I am confused as to why this error message is appearing.
I've tried copying the .mp4 to my VIDEOS folder on C: drive with the same result.
Some research has suggested to run the Photos app as Administrator, but I can't figure out how to do that.
Any suggestions on how to trim a video would be appreciated!
Thanks,

 

Windows native photo/video viewer (Microsoft Photos/Movies & TV) does gives error (0x80070057) when trying to trim or otherwise edit videos on external hard drive.

This is an expanded question based on a previous post that was never adequately answered, with similar questions frequently asked. I would have replied there, but the thread was locked.

Similarly to the linked post, I was attempting to use the trim feature found in the Microsoft photos and video applications to cut out unnecessary parts of a video. The video was stored on an external hard drive, along with other photos and videos to avoid filling up the internal hard drive memory on the computer. When I attempted to trim the video I received the following error message:

"Photos

Please try again. If the problem continues, visit https://support.microsoft.com to check for guidance.

0x80070057"

I've tried to include a screenshot of the error but it doesn't seem to be going through.

I reset and repaired the Microsoft Photos and Movies & TV apps from the advanced settings on each app in the applications menu. Then tried uninstalling and reinstalling Microsoft Photos using admin console of Windows Powershell (based on instructions here). Neither of these methods were successful. On a whim after reading through the initial post I linked, I tried moving a video from the external hard drive to my desktop and the trim command was able to function. My question here is why does the app not work for files on an external hard drive? Editing photos there works fine, videos are the only issue. There is no reason I should need to move GBs worth of video files over to my laptop's hard drive just to be able to use a basic function of a built in application. It seems like this may be an ongoing problem from searching community forums, and is worth addressing.

System Information (only the basics listed here, if necessary I will provide more information):

Laptop: Dell Inspiron 15 5593 (from 2019) running Windows 10 Home build 19045.2604

External Hard drive with photos and videos: Seagate OneTouch 2TB portable HDD

As a final note, I want to stress that I have outlined the steps I have taken to address the issue thus far above. I do not mean to be rude, but please do not respond with a suggestion to do something that I've described above or was in either of the linked posts. That is not contributing to solving the problem.
