Windows 10: Photos App. Video Editor cannot find files

I've been using the Photo Apps Video Editor to create a travel movie. The project has taken me months of work. I updated windows and now I open my project and almost every single video on the timeline says "cannot find file". The original files were never moved and are still in the same spot. I will add the file into the library and still no luck. PLEASE help. The movie is 3 hours long and has taken me months!! I backed up the file halfway through and it works, but I don't have it in me to go back and edit thousands of small video clips. This is insane. Also, my computer is unbelievably slow after this update!!!! FURIOUS

How do I Remove Video Editor and Connect?

Video Editor is part of Photos, I'm not sure you can just remove that and leave Photos in place.

For newer apps not yet listed in the tutorial, see Step 4 to find out the names of all the app packages, then you'll know the names to use in Powershell.

 

Video Editor in Photo app

The video editor is built right into the Photos app. So, if you have the photos app installed then you also have the video editor. If it is not showing in the start menu then Please open the photos app and look in the topmost options. You will find an option
"Video Projects". Click on it, the Video Editor will open.

Please suggest me a very good video editor and a photo editor (although inbuilt photo editing is there but still if there is any better) for my nokia 808 pureview white and from where i can download these and install in my mobile.



Thanking you,
