Don't know what is up, but when starting a new project today all my new video imports (HEVC, ,mov files) do not show up as readable. I can import past videos from past projects and they show up fine, but my videos from my last shoot just do not register as video files. They get the file icon, but act like files that can't be properly read as videos. When I open them in the trimmer (or drop them in the timeline) there is just a black screen, but the audio plays. The video files seem fine, I can open and watch them in my window pc's media player, and they were shot with my usual camera.

Attached is a screenshot of the non-working new video file, in a project. Next to it in the timeline is a video file I've worked with in the past, which is showing.

I've uninstalled and reinstalled the program. I've updated my pc's software.

The computer does seem to labor when creating the Movie Pro program files on import, more than usual. I'm on a Lenova Legion Pro laptop with plenty of processing power.

edit in: I've noticed that the project media folder is having trouble consistently displaying the preview icons for even older videos that are working in the project. They just show the fixed icon and no image preview. If I hover over the working files the preview will come on, but will not remain. The program seems to be having a problem overall in displaying images.

Any help would be really appreciated.
