Black flickering of the image

Hello, a few months ago this error occurred from one day to the next. I have not made any update, nor changed anything else.
The problem is this : When playing back in Premiere Elements 22, but also when I export the video to for example mp4 there is always a black flickering of the image. It is completely different how often and where it occurs. Very like the error is at transitions or also for example at green screens. But it can also happen in the middle of a video track, as seen in the picture.
I have already reinstalled Premiere Elements and downloaded the latest graphics drivers. It seems to have decreased a bit, but it is still far from fixed.

Has anyone had the same problem and know of a solution?

Thank you for ur answer!
