Video frames de-sync with OBS and Decklink Mini Recorder 4K

I faced the problem with video frames de-sync. It will be easier to explain by showing a couple of screenshots (in attachments). Screenshots are made in VLC from recordered stream.

My OBS PC setup:
Windows 10
OBS Studio 25.0.8
Decklink Desktop Video 11.0

Blackmagic Decklink Mini Recorder 4K capture card connected to my separate PC by HDMI. PC has 144hz monitor connected via display port to NVidia GTX 1660 Super. Frames de-sync visible even in OBS preview. From my last 5+ hours stream OBS showed only 2 render and 1 encoding frames drops.

What it can be?

Thanks!
