Gradually worsening lag in PP as copying from one sequence to another

[keillerWSU84]

I've seen another similar thread where one of the Adobe moderators noted this issue had been resolved in the latest update - but I'm still seeing gradually worsening lag as I'm copying clips from one sequence to another. If I restart PP then performance is fine for a couple minutes then reverts back to being laggy. 

I'm using a top spec M1 Max MBP (64Gb RAM) and 23.2.0 PP.

No significant lag when playing clips, just when copying/pasting and moving between sequences.

yeah, problem is still persistent, i still lag a lot after some edits or copy and paste
