Logic Pro 11 crashing on play after update

At this point, I'm sort of lost. I think that it has to do with some 3rd party plugin that I'm using. But if I start a new project and insert my 3rd party plugins, the project will play fine. However nearly all of my older projects are crashing the minute I press play. Spinning wheel sits forever, Logic application not responding. I checked my computer diagnostics and it seems like my mac is running fine, even when it crashes.

Looking for any new ideas to try to fix this issue.
