Can't plug-ins added when selecting output channel settings in Logic Pro 12.3.1

After a long week of troubleshooting, I reached the conclusion that the app pre-sets for the output channel have somehow become corrupted or broken. Since I could still insert plugins manually in all channels, including the output channel, I created a simple work around. I opened old projects which already had the output channel plugins already with the plugins I want. Then I saved the sets on each as user defined presets. Now I can use them the same as before without any issues. Now I have time to worry about fixing the problem at a later date.

Thanks to all who have responded,

Yes. But it wouldn't matter. The problem is that even the modern app presets won't populate the channels plugin slots. But I've noticed that in some cases I noticed that, Setting> app presets> Knock A, creates a new channel strip with the plugin slots populated. ?!

In the output channel > Setting > (drop down) choose a preset such as Knock A Knock B . . . or a legacy preset such as Basic, Classical, Jazz, etc. / the slots fill with plugins . . . or at least they're supposed to.

When I choose Setting > Drop Down App Presets > Knock B, nothing happens. The slots are still empty . . .

Thanks for jumping in on this . . . I'm really baffled by this issue . . . it's almost as if there's a virus.

It's with old projects that once opened and operated as expected, new projects from scratch.

I haven't tried logging in as another user but I've tried just about everything else, including components, plugin manager. The behavior is like certain settings may behave correctly while others don't . . .

I'm considering uninstalling Logic and doing a clean re-install . . .

Hi

Possibly associated with a macOS(?) update... if this is the case you'd need to consider waiting for an update (OS or app), or perhaps downgrading your macOS ( this is a big job, not sure i'd do it just for this issue alone).

Could you pls confirm the Mac specs, including the exact version macOS

Mac mini M2

But the recent update I was referring to was for Logic, which I updated on Sept. 8

Thanks for all your help . . .

Wow! So they actually put that in the release notes . . . so, apparently it was a bug? I wonder if calling Apple last week and pointing it out had anything to do with this. Hmmm . . .

Thanks for the heads up!

Ok, I’ll take your advice

I think the timing of the last update on Sept. 8 coincides with the emergence of this issue, but I'm not entirely sure . . . ?
