The same plugins that were causing Cubase 10 to crash for me, still cause Cubase 10 to crash with the 10.1 update. Hopefully they’ll eventually fix this in another maintenance update but I’m starting to worry a little as I thought this would have been one of the first things to be resolved. If they work in 9.5 and in Cubase 10 when running in 8.1 compatibility mode, I see no reason why they shouldn’t run in 10. I speculate that something must have changed with how Cubase interacts with Windows 10 and VST plugins that is not happening when running it in compatibility mode or on other operating systems.
