Focus problem for EOS R5 Mark II and 200-800 lens

Hi, I an having issues with focus with my R5mk2 and the 200-800 lens, the lens seems ok on my older R5, and my 100-500 lens seems to be focusing fine with my mk2.

I had an accident, the tripod fell over, it all seemed fine for two weeks, but recently the images are blurred, and at times it is not recognising single point with tracking, just treating it as single point, and also at times trying to focus all over the view, despite me having that option turned off.

It usually seems to follow the subject fine, and looks locked on, but the results are too soft to use.
