AW3225QF, input lags

I have used the monitor for a few weeks and everything was fine. But then I have decided to use USB inputs for keyboard, mouse and webcamera. I have connected them to the USB outputs on the monitor and then connected monitor's USB-B to motherboard output.

The issue that when I'm enabling webcamera and sharing the screen in any application (Teams, Google Meet, Slack, etc.) the inputs starting to freeze every 5-10 seconds, both for mouse and keyboard. Mouse not moving for a few seconds, or keys are ignored or typing 20 same letters in a row...

I have tried to update firmware to the latest (M2B107) - doesn't help. The cables are the ones that were in the box with the monitor. I have tried to switch USB cable to another one - same result.
