Happens with any random 3rd party plugin at random times.

I think this happens when using silicon-incompatible plugins.

yes, i see this from time to time .. called apple .. they are not sure why either .. I am still trying to figure it out ..

I get this when moving UAD Native plugins around in the mixer

It's just happening. And wellknown. Very likely, Apple's new way of treating plugins in a separate process is the culprit as it never happens in Rosetta mode, where plugins are treated the "oldfashioned" way. Nothing to do with Intel plugins, either, I have none installed anymore.
Sometimes you might be able to single things out by opening Console and the crash report entry on the left. But very often it doesn't show a single plugin this might be related to.

Yeah, I’ve had this happen once or twice recently over the last month or so. It’s happening in Pro Tools too (albeit with a differently worded error). There’s a feeling over in their forums that it’s an iLok issue that needs to be updated.

There's only 4 plugins using iLok on my system (some UA stuff) and I rarely use them. So I'd say it's defenitely not just that.

🤷‍♂️

I'm sure you've tried a shut down and restart - I get it if there's an old plug that needs an update or a new install that needs authorising - or a demo file conflicting... and it can infect other non-relevant third party plugs as a result - so tricky to track down the culprit

Well, in most cases, when I click "Recover", things will work fine for a while.
In case they don't, restarting Logic will do the job.
And in case things happen too often, a computer reboot will give me some more "leeway".

It's really not a reproduceable thing, it always only starts to happen after an undefineable while and it might be related to some strange "RAM clogged up" or whatever issue.

Or it's just related to the new way of Logic treating plugins in a separate process, because it's happening exactly never once I run Logic in Rosetta mode (which is also fixing some other issues I'm experiencing every now and then). And no, it's got nothing to do with Intel plugins, either, I have none of them installed anymore.

Really, I'm absolutely sure there's something fishy with Logic's new plugin operation mode as the issue only exists once you make use of it. Pretty awkward, a feature supposed to increase stability when using 3rd party plugins is actually doing the opposite.

As I say, it’s happening in Pro Tools too.

I'm not denying there's iLok issues - but in case of Logic, it's certainly not the only reason for it to act up.

this is the first i have heard of this ... iLok issues ... hmmm ... i cannot replicate this YET in PT ... will keep trying ...

There's quite a few posts over on duc.avid.com about it. Apparently iLok have acknowledged the problem.

If that's the most annoying thing that's ever happened to you, then I envy you....

Is this still happening and does anyone have a fix if it still is?
It’s impossible for me to work in 11 as it was happening to me all the time so I just work in 10 with Rosetta.
It’s too time consuming to go through the wait and find out only to find out that I found out - again - that I have to jump through hoops to get it working again… only for a short time before I find out….
I imagine that a few of us here have quite a substantial amount of third party plugins so troubleshooting - by filtering out possible culprits - is not an option.
Why Apple haven’t sorted this out yet is more than a little irritating

Not sure whether it's got to do something with the Sequoia updates or because I might use some slightly different plugins (which always sort of happens over time) but I'm getting a little less of these messages since a while. They're still coming up and they're still defenitely never coming up in Rosetta mode, but at least it's somewhat less. Still not a great Logic version for various reasons.
