This is a few years later. But I’m running Logic on a Mac Mini (2018) with Catalina OS. I’ve tried the cache deleting options, though my system does NOT have an “audiounits” related item in the library. Nothing with that name string.
In logic under Plugin Manager “Toontrack” does not appear anywhere, not in lists of plugins, not under “Manufacturers”.
I re-installed the Toontrack product manager today and updated everything.
