Pause play issue with fuzzy frame

Same issue as some people have reported. Premiere is unusable as the following type of image appears every time I pause playing either on the time line or on the clip itself. Have tried all issues suggested on various similar posts. It worked fine when I started this morning, then the wheel of doom appeared and the whole computer crashed. When I re-opened Premier Pro 24 or Beta, the issue appeared. Is it one of these programmed obsolescences because it puts me in a really s***y situation as I cannot finish the job? 🤬🤬🤬🤬🤬
