I am running macOS Mojave 10.14.6 with Pro Tools 12.
When Pro Tools tries to load sessions where ANA 2 is present, it gets stuck on any track with ANA 2 and loads forever but never opens.
The only work around is to open the session with all plugins inactive and manually activate them one by one. But even then, I cannot activate the ANA 2 plugins or it will freeze again.
I can load a new instance of Ana 2, just cannot recall previous instances without freezing.
