Cubase 10.5 and Kontakt crashing

Hello,

I have my Cubase crashing when using Kontakt libraries, this happens very frequently.

I saw that someone posted their crash log and Martin took a look, Martin or anyone else from the team could you please help me? I can barely work on projects and have no idea what to do

I will appreciate any help thank you very much

I’m attaching the crash log here.
Cubase 10.5.0.68 64bit 2022.5.16 20.52.14.998.dmp (3.0 MB)

This isn’t that helpful to you, since it just confirms what you know, that the crash is in Kontakt’s VST3 plugin.

Buit here’s the analysis from WinDbg Preview, a publicly available utility from Microsoft.

Hey Steve thanks a lot for your response

I understand, what would you recommend to do next, install another version of Cubase (11) ? Another version of Kontakt? Since it happens randomly every 20 minutes it’s difficult to troubleshoot blindly. Do you have any experience with something like that?

Thank you again

Is there maybe a way to know which vst plugin causes Kontakt to crash?

It’s hard to say, but maybe check in the Kontakt forums?

Kontakt is the plugin. Inside Kontakt you have the Libraries.

Maybe disable all Kontakt tracks, and enable one-by-one?

I see ok I will try this way thanks!
Just one last question please, technically speaking if I freeze a Kontakt track, this track can’t trigger Cubase to crash the way it currently does? I mean technically it will be played back from an audio file by Cubase and therefore won’t crash?

I would not answer that, since I don’t know your system.

Give it a try. It takes very little time to save a copy of your project and test.

But unfortunately there are times when it doesn’t crash for a few hours, I would have to disable each one and test for at least a day, but if there’s no other choice of course I will try this

I’m sorry, earlier I wrote plugin and meant library - just to confirm, the dump file doesn’t give any clue to what library caused the crash?
Thanks a lot for all your help

Just a heads up that there’s a Kontakt update in Native Access that I just installed, and although I’m using C12 and you’re using C10, it seems to have resolved my CPU overload issues I was having. Check Native Access for a Kontakt update and then report back. If you’re already using the update, let me know.

Thanks yeahimsteve! Do you know what Kontakt version you updated to? Just to be sure

Yeah man, it looks like 6.7.1 (R0). I am using the Kontakt 6 Player, although I do own Kontakt 5 full version. Another thing I would suggest is that if you’re using the full version of Kontakt 6 and there’s no updated version shown in the Native Access app, to try the Player version, just as a troubleshooting step. Unless you’re not using official libraries and require the full version of Kontakt. But I’m using the MM-Bass library so it works in either version.

That’s interesting mine is 6.6 alright I’ll give it a try maybe also the player version, if I ever find anything I’ll report back thanks a lot!

Yeah I think I had that 6.6 version prior to this update, which was causing me problems. Hopefully the update sorts out your crashing issue.

I mean problems and bugs should be sorted out by the vendors, but Cubase should still not crash, even if the plugins crash. Would be nice if you could leave a vote here if you think the same:

Solution to crashes by plugins - Sandboxing (Crash protection) - Cubase - Steinberg Forums

Hey guys I think I found out what the problem was, I think it’s not a specific library within Kontakt, it’s actually the use of purging samples. I tend to do it in many libraries and it seems that if you do it too much it causes Kontakt to crash Cubase in a totally random fashion.

Once I reloaded the samples in some libraries (not all), I don’t experience any more crashes.

Maybe it’s a bug that was fixed in a later version as yeahimsteve suggests, I’m honestly afraid to even upgrade now that it’s working fine

Hope it can help someone

Unfortunately it’s still crashing, for some time it was much less, but now all the time

Upgraded to Cubase 11
Upgraded Kontakt to 6.7

Nothing helps
