First thing, move all plugins to unused folder and relaunch PT. Stock plugins will be copied back but anything else is not usable. If the performance is satisfactory, then start moving plugins back one vendor at a time.

You will notice when you get problems. Remember, you do not need to use a bad plugin in a session, it only needs to be loaded into memory to cause random errors. Once you find a problematic vendor find updated plugin installer or stop using those.
