"random crashes" is not specific enough for anyone or even the developers to address your issue

How random? what where you doing at the time , the setup /inputs , error logs , driver updates etc

Yes, this evening. Still on .58.
With 2 systems that where rock stable untill now. With with a ryzen 5800x + quadro rtx4000 combo. Going to look in the logs when home.

I alos get a lot of these:

24.0.0.59 - WINDOWS - 09.06.2021 16:03:06
========================================
Error disabling WindowsUpdate: vMix.vMixServiceException: vMix Service Not Ready
bei vMix.vMixServiceClient.Startup()
bei pzzzzzs.w()
========================================

But I guess that's not the issue.

I wish I could give a step by step, but it just randomly happens, even when just sitting there idling. I checked the logs some more. This type of entry only happened once after the last crash. before that, there is nothing in the logs that I can find that keeps reappearing. The only common thing is, that they are running on the same network and they are running on the same network and we recently

Random crashes are going to be hardware related most likely, so the vMix logs will not be much help.
You can look at the Windows event logs to see system issues and crashes in other apps potentially, to help you narrow down what hardware is at fault.

In the rare case it is an NDI source, you can tick the "FEIM" box when adding each of them. Then if one of the sources crashes
it will be reported in the vMix logs so you can then contact the manufacturer of that source for a fix.

vMix

I have about a dozen systems running that I've built. Since v24 has been out the new systems have started there and have been fine. Most of the older system, on v23, are closed systems that don't have a need to upgrade. Once system though, at a church, I upgraded to 24 in hopes of using the focus settings for PTZ Optics cameras. After I upgraded to 24 (I don't remember exactly which sub version) vMix started closing randomly. The only change was upgrading to v24. I down graded back to v23 and the system was fine. A while later I tried it again. That time I also updated the PTZ Optics cameras and BirdDog Mini connected to the system. I know that the BirdDog update included newer NDI support. The system was much better, but vMix did close once which pushed me back to v23 because I didn't want to take the chance. I did work for much long before closing. This particular system also has a ProPresenter 7 Mac sending via NDI. Their change log shows the last NDI update being to v4.5.1 last year. They show they have addressed NDI issues since then, but I don't see any newer version update.

I haven't posted about this because I haven't had time to try v24 again and be ready to switch back to v23 for production. (I am also building them a new system but stalled waiting on a video card.) Is it possible that the NDI update in v24 is having issues with older NDI versions?

This system's spec are:
i7-4770
GTX 1060 6GB
16GB System memory
1080p30
2 NDI cameras
1 ProPresenter via NDI w/ overlay
1 USB HDMI input
2nd video card out to projectors
NDI out to BirdDog Mini
During production recording and 1 stream out

Still running stable on both machines until now, running shows every day. I guess in my case the culprit was the NVDIA driver
