After v.8.5.10 it crashes a lot here… 
I think it has related to Variaudio, maybe…
How could I revert to v8.5 on OSX?
I tried to open Cubase without the option to disable Preferences, but without luck…
Today, with a small project it crashes each time I stop a recording track…
I took almost the plugs…
So, I don’t know what’s happen here… 
I bought another system hd, and I did a clean install.
1st I just installed C8.5 then UAD, Waves, Soundtoys, Fabfilter, Melodyne… All my soft is legal.
Then I open a problematic project, that crashes always on a spot, and it crashes again…
I tried to bounce the song, and it crashes again on that spot.
Then the problematic project is obviously corrupt somehow.
I have had a similar issue that may or may not help with this workaround…
Try opening a simple project first. Any basic Cubase template. Leave it open and then open the problem project while Cubase is still open. Activate it and save as a different filename.
I have saved a project that had similar crash issues by doing this. It only happened once but this worked somehow.
Never again did I have the issue. Worth a try maybe…
Probably a specific plugin…use the rename vsttplugins folders trick to confirm.
