Hi,

For the past two days, I've been experiencing freezing and crashing issues with VMix during live streaming.

Processor: Intel(R) Core(TM) i9-14900K (3.20 GHz)
Ram : 64 gb
Nvdia GeForce RTX 4070Ti
2 camera with black magic decklink card and 1 vmixcall.
My system ran perfectly till last week.

Youtube 1080p 7mbs AV1

Before the streaming, everything worked fine. However, 10 minutes after the stream started, I was unable to control VMix. The Vmix panel froze. I couldn't change the sources, cameras, sound, etc. The FPS dropped (15-17 fps), the render time increased (100-125 ms), but the GPU (%1) and CPU (%5) remained stable. However, pc ran perfectly and the streaming continued uninterrupted till the end of the show.
After the event, I made a test stream and encountered the same problem. But this time I was able to control VMix via Stream Deck. fps and render time issues continued.

I don't have any issues when recording.

What could be the problem?
