For later experiments (such as kernel 6.6.9), did you also confirm this after
SER happened? Maybe, you can a ping with timestamp in background:

   ping 8.8.8.8 | while read dt; do echo "$(date '+%Y-%m-%d %H:%M:%S') - $dt"; done

The path to debug SER dump is longer, because I personally don't understand
the numbers, so I will need internal experts to help analyzing your feedback. 
Since RTL8852AE is earlier chip, the progress will be slower. So be patient
if we choose this way.

Personally I prefer to bisect kernel first (though it takes time too).
If the cause isn't from driver side, let's move to debug SER dump.
