We don't have a list of all the plugins. We've had experiences with Keen Tools causing the issue that causes the server to not startup correctly. But there are definitely others out there.
Let's see if we can get some log files.
Open AE
Help -> Enable Logging
Restart AE
Attempt to use the camera tracker to the point of failure
Help -> Reveal Logging Files
Find both the After Effects Log.txt and AnalysisSelfLink Log.txt files and post the contents of those files back here for us to review.
