Windows 10: Is there anything I can do to get trim to work in the photos app?

When I save after trimming in the photos app, it will load forever/ wont save. I have tried all the troubleshooting methods including: repairing in settings, restarting in settings, uninstalling and reinstalling via Terminal Admin. I have chatted with a friend and they have the same issue. Clipchamp works fine but requires me to pay if I want to clip in 4k. I find that unreasonable as I purchased my device with 4k and the ability to trim in 4k, but am now being guided to a new app which requires me to pay $129 CAD yearly. I don't need a fancy app, I only want to ability to trim down my 4k vi

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,
