Your symptoms are screaming "broken plugin". Focus on that.

Yes its nice they are up to date, but that does not guarantee you don't have a bug or mangled plugin or plugin file you missed. You need to try the standard troubleshooting step of removing all third party plugin files and seeing if the problem goes away. Just drag *all* the aax plugin files out of their standard directory to any old directory somewhere else, Pro Tools will put back the standard system ones. If the problem goes aways, start putting putting them back in batches until things go south. Yes a plugin only needs to be loaded, not even instantiated/used in the session to cause problems.

Also try a new empty session (not from template, not a copy), and trash prefs and databases.

If that does not fix it, post a Sandra report. See the "Help us Help You - READ THIS Before Posting!" above on this page.
