I've been running vMix over the weekend with a medialooks receiver pulling in 2 x 1080p25 feeds. The test was really to see how medialooks behaved, but what I found was vMix would randomly quit. No error message from vMix - its like a graceful quit.

I had a look in the windows logs, and there is an error and info logged for vMixNDIHelper crash and then vMix Crash. Anyone have any idea why this is happening?

Thanks

Jonathan

Greetings!

Until this days, crashes of vMix64.exe while receiving NDI was observed only on fresh win10 (like 1909/2004 with all updates).
on ltsc it was fine and stable.

few days ago ltsc was updated by kb4571748. and now vMix with NDI inputs crashes on ltcs too.
reproducibility - 100%. but times may vary from few hours up to few days.
