Ever since Premiere 26 I've been having issues with the tracking

Ever since Premiere 26 I've been having issues with the tracking, specifically for work I use perspective corner pin tracking for applying written text to a white board every month or so. We draw black dots in each corner for After Effects to track and apply text in the form of a PNG that matches the board’s aspect ratio after tracking. 

However, since moving to 26 I’ve been finding that after 5 or 6 frames it starts to drift out from the tracking dots and then it loses it entirely. jobs have been done essentially babysitting the software every 3 or 4 frames with the end result looking not quite as smooth as I would’ve liked without a lot of going back in and adjusting frame by frame, which isn’t the point of this software at all. 

Same problem on 26.3, in fact there was an additional problem that kept coming up with “media smaller than previous frame” or somehting like that, and then would refuse to analyze next frame

Going back to 25.6.6 I’ve been able to do the last 3h of work in the 30 minutes
