I have the same problem - used to be ablwe to playback at full resolution on Studio 2 Max even with massive project size - now completely locks up even at 1/4th resolution - tried deleting media cash (all), moving cash locations, restarts, importing sequence to new project etc. nothing works

Do you by chance have in Preferences\Timeline your Auto Scrolling option set to Smooth Scroll?

If so, set it to Page Scroll and give it a try.
