Pixelated video when previewing new project

Picked my video file for new project. Go to work on it. When I hit play to preview the video file itself to start editing/rendering etc, the video plays very pixelated. Before hitting play, and the first frame is visual, it isn't pixelated, but hitting play, it goes crazy. It is happening to past video files too, so it isn't the newer video files. I've played it in all qualities: low medium high. I've unselected and reselected optimize video. No change. Ive cleared the cache and disabled hardware offload and enabled it again. No changes. It only occurs when I'm trying to use premiere rush on my HP laptop, which I've done projects on before and it works. I did update rush, and that's when it started. I don't think I updated my mobile version, and it still works. Is there any way to get a version on desktop that doesn't include the update, or is it not an update issue? Below are pics of the issue
