Been offline since my last post until recently but many of my problems have been resolved by the latest version that came out a week or two ago. Pr is not crashing anymore, in particular when trimming clips, which would almost guarantee a crash. The other thing I did was buy an external SSD (Samsung T5) and this has helped significantly. Pr is still slowing down when I start layering multiple 10 bit or 4K files. One strategy I'm using is to do adjustment layers and text last because they really slow things down, as does warpalising. My timeframe still stalls by the end of one of my projects (normally 15mins in length, made up of 10bit and 4K footage) so it's easier to render a sequence rather than trying to play it, which is still a pain, but at least it's not crashing any more.
