Sound crashes after 45/60 minutes of streaming

[VALROK]

I am having serious issues with Voicemeeter Banana.

I have been streaming with a separate streaming system since january or so without any issues. This was until around 3 weeks ago or so, where randomly, the sound that's sent through the capture card via HDMI AND my microphone that's being sent through VBAN to the streaming rig, "crashes"/bugs out - on stream - after roughly 45 minutes/60 minutes of streaming. This is a consistant issue.
I am using Streamlabs OBS to stream to Twitch from my streaming rig, and as far as I can tell, it's only the scenes with the capture card feed enabled that's bugging out. When I switch to a "Be right back"-scene, my microphone is not bugging out, but is performing as expected. It appears to only affect audio coming from my gaming rig (i.e. music playing from my streaming rig is not affected).

I have set the VM input and output as the default devices in Windows (10) and checked the samplerate - 48k all around. My Voicemeeter Banana settings are as follows:

The only thing I can think of at this stage is that Elgato 4k Capture Utility updated the firmware of my capture card a while back. Windows 10 also updated, but I followed every tutorial to make sure nothing had changed with the sample-rates like the issues described in here. I have tried reverting to an older version of the firmware of the capture-card, but I just don't think it's what's causing the issue at this stage.

When the sound "crashes"/bugs out, NOTHING is indicating this on the mixer-view of VM Banana on either the streaming rig or my gaming rig. It appears like the feed is coming through like it should at the gaming rig, when visually monitoring the desktop audio and the microphone levels. I can hear the desktop sound clearly and without any issues through my headphones on the gaming-rig.
Restarting the audio engine doesn't do anything to the issue, but disabling the capture card and enabling it whilst also restarting the audio-engine has about a 1% chance of clearing the issue on-stream.

It is getting really frustrating being told Someone PLEASE help me.

Thanks,
VALROK.

Do you have updated Banana also (before the problem has started)?

No doubt, you are a very experienced and advanced (expert) Voicemeeter user, who definetly knows what he is doing.
In the end, if you have used the exact same settings without any problems since January and everything was rock stable until 3 weeks ago, then everything points to the (automatic) updates as root for all evil.

I do not actively stream, but based on my experience in music production where we use systems that are offline (with disabled automatic updates) and only connected to the net if a software must be activated online:

Besides necessary security updates, try to avoid other updates (especially for drivers) if you need a stable system that works every day.
Only update drivers if you run into trouble with the ones you are using.
I guess you know it, but in the old days we always said: "Never change a running system!"

If the issue was windows updates, then you will be able to find the corresponding update in the update history, and remove it. (Settings... Update and Security... View Update History (Find update which was installed right before the issue occurred) ... Uninstall Updates)

Disabling windows updates is generally not advisable. Stability and security updates should be allowed. The right way to deal with unwanted updates impacting system stability, is to disable driver updates via windows update (and manually ensuring that you are running the most recent drivers, as security updates in drivers are commonplace, so put it in your calendar to check regularly), and most importantly, to set windows update to prompt you to download updates.

In spite of the common hatred for forced regular updates in win10, that's never actually been a thing. There has always been the option to have windows prompt you before downloading updates, and to prevent it from updating drivers.
