Stand alone and in-DAW MIDI Bass works but MIDI Guitar does not

My MIDI Bass works both stand alone and with Logic. My MIDI Guitar 2 does not see input signal from the interface with the exact same settings standalone or with logic. Both VST and Component Files moved to appropriate folders. Interface is Presonus 2626. Weird to work in Bass but not Guitar. I have used this on a separate license on a Win10 Machine with no problem both stand alone and in Cakewalk, Studio 1, and Mixcraft for years. Any ideas?

Nothing changed here in a very long timeā€¦ licenses have no role in this.

Maybe you have the older MacOS 10.14 AU/component for MG but the newer for MB (or the other way around) - did you recently update MacOS?
