I'm having this same issue for the second time. The first time I able able to fix it without having to move all my plugins but unfortunately I don't remember what I did. After updating to Automap 4.8, the issue has returned. So I suspect that Automap may somehow be the culprit. Ideas?

Oddly enough, after I moved the plugins out of the Component folder and then moved them back one by one, Logic starts up normally now and the component folder contains all the same plugins as it did before completing the process. *shrug*
