for us it doesnt load the soft synths in the project we can load them manually after boot but all patches and tweaks + fx chains associated are lost when the synth is re load thousands of hours of work lost its a financial disaster for my client as we have tried to uninstall and go back but the damage to the files stays and reinstall of the old program still presents the same issue maybe someone can find a way to clear the registry so we can go back
As per my other thread I've gone from 10.3 to 10.5, having loads of issues with VSTs which previously worked fine. I'm in the process of finding out how to downgrade back.
