And looking at your plugins very quickly, lots to want to troubleshoot there, esp. Slate VMR, old Ozone 6, etc. we cannot guess what you are doing in VMR. Try removing all .aaxplugin files, and restarting (Pro Tools will magically reinstall its own default plugins) if that is rock solid, try putting back say VMR and seeing if that works.
