slow load between projects

Anyone else experiencing long load times between projects in CBP10? Recently seemed to be about 2-3 minutes going from project to project. 'Thought it had froze, but eventually finished opening.

Mac Pro 2012
3.2 GHz Quad-Core Intel Xeon
48 GB ram
High Sierra 10.13.6

YES! my current big project which has opened rather quickly on 9.5 has taken 36 MINUTES to open on CB10 yesterday! ridiculous. hope there’s a fix for this in the next update.
