Really odd behavior TBH.
You previously wrote that ANA 2 was working inside FL Studio, could you please check if you can see & use the AU ( Audiounit Plugin ) or only the VST & VST3 inside FL Studio ?
You could give a try to one more ANA 2 installation after re-installing Logic, preferably following the manual uninstall procedure as explained before, but honestly this is a very odd behavior.
Wonder if this could be something specific to your Hard Drive file format, MacOS permission settings or your Mac model specs.
From the Disk Utility app on your Mac, you can select your system HD and display the "info" to check the file format, on a recent Mac it should be APFS but check if there's a mention of "encrypted" or/and "case sensitive"
More info here :
- Also, we already have your MacOS & Logic Pro version but what's your M1 chip Mac model & specs ?
( i.e : Macbook Air ? / Mac Mini ? --> Apple M1 Chip with 8-Core CPU & 8-Core GPU ?? )
I will check this with S.A team on Monday, meanwhile info about your system HD file format and Mac Specs could be useful to troubleshoot this further.
I'm on an older version of Logic here but what happens if you try to open this project ?
( it's just a 1 channel project with an instance of ANA 2 v2.0.98 using the init preset )
