3rd party plugins greyed out in logic 11.2 during session

I've noticed since updating to Logic 11.2 that many third party plugins are greyed out during session and when re-opening a project. I had an instance of Serum 2 loaded on one track and then duplicated the track while I was browsing presets and wanted to create a new track with that preset loaded. Normally in Logic 11.1.2 these tracks would be duplicated and Serum 2 loaded and available on the duplicated tracks.


In 11.2 the duplicated tracks are greyed out and I cannot get the plugin to load by double clicking on the greyed out instance. I have to manually reload the plugin and find the preset again.


But when I save and reopen the plugin these tracks are once again greyed out and require manual loaded of the plugin again.


It's not just Serum 2, but any of my third party plugins are also impacted by this issue. I've looked online and seen many other people report this issue, but cannot find any answers that resolve this issue.


I've downgraded back to 11.1.2 but would love to know how to get 11.2 working without these greyed out plugins, which totally destroy workflow and the ability to recall projects. Any assistance would be greatly appreciated.

Mac Studio (2022)

It seems it is a 3rd Party Plug-in issue (with 11.2). I am basing this on the last couple of weeks. So many people have posted about this single issue. I can tell you that it runs much smoother on 11.1.2 for sure and does not happen as often for me on my main rig. I am 💯 staying one version behind (for a while).


When I Produce, I am heavily dependent on 3rd party tools. Logic's plug-ins are useful and impressive but I choose to work with other tools as they have become a staple of my workflow. For those of that need to use other tools, we simple cannot move forward with efficiency.


The question is...

Is this Logic Pro's issue or

The manufacturer that you bought your plug-ins from? 🤔

I have already helped a couple of folks by doing this.


I would remove all 3rd party plugins from your components folder to see if this is an issue outside of Logic Pro. Simply save them to a folder on your desktop. If you need me to show you how to do this, just let me know, and I am happy to walk you through it. BTW hold CMD as you drag these files out so you do npt duplicate but rather remove them from the Components folder.


Logic Pro 11.2 has been kind of tricky so your troubleshooting needs to be methodical.


Once everything is working smoothly. You are going to have to insert components Alphabetically or by Manufacturer. This is what I did and I was able to locate the problem. I dragged in every plug-in that starts with the letter "A" and then I would up up Logic. If everything went smoothly, I would then quit Logic Pro and drag in the next letter "B". Open up Logic Pro and if Group "B" went well, you can continue on with this experiment until Logic Pro hangs. Once things start getting wonky, you can surmise that this is the group giving you the issue.


This is the only way to see which plug-in is potentially causing the issue. If you need screenshots LMK and I will provide.

I'm having this same issue. I already used the link to report to Apple. Any session I have that used any of my UAD plugins (which are all the latest versions), Kontakt (again, latest), or Soundpaint (latest) causes the same crash mentioned here. I restart Logic in safe mode and it tells me that they are all unavailable on my system.


Then I used the plugin manager and had it do a full rescan. It finds all of these plugins and deems them "successfully validated." I can then do a new test project and use any and all of them with no problem. But the minute I close that project and reopen it, crash, with same error code. I'm at a loss.


I have no way to revert back to 11.1 unfortunately.

The temporary solution was mentioned in this thread:

  1. Revert to 11.1.2 (If you have a back-up copy) or
  2. Remove all 3rd party plugins from your components folder to see if this is an issue outside of Logic Pro. Simply save them to a folder on your desktop. If you need me to show you how to do this, just let me know, and I am happy to walk you through it.

Since installing the Logic Pro 11.2 update, 3rd-party instruments are gradually becoming unavailable for loading in projects.


I am on a 2022 Mac Studio running OS 14.7.6, all of my apps are up to date, I have allowed full disk access for the 3rd-party companies that require it. All of my purchased plugins and instruments show installed and ready to use in Plug-In Manager.


I have restarted the computer and Logic innumerable times. I have reinstalled the latest versions of all of the "missing" plugins.


Initially, Native Instruments' Kontakt 8 showed installed and ready to use but was no longer in the AU instruments drop down menu. Yesterday, Audio Modeling's SWAM instrument library went AWOL and IK Multimedia's SampleTank 4 just disappeared this morning.


Is anybody else experiencing similar issues with 3rd-party instruments since updating to LP 11.2?


If you have a solution, I am all ears.


Cheers!

Thanks, Eddie.


I neglected to mention that I had attempted the time-consuming components solution on day 1 of the 11.2 update because I'd also lost all UAD instruments. It did not work then so I have not gone through the trouble when the other 3rd-party instruments disappeared.


Unfortunately, I can no longer revert to 11.1.2.


Why would virtual instruments that worked for weeks in 11.2 (SWAM, SampleTank, & Kontakt 8) gradually disappear over a span of a month and not immediately all at once?


Oh well, recording will have to be idle until a future update resolves the issue (or I'll switch to Cubase or Studio One. ;-) ).
