Host GPU goes black, after passing another GPU to guest

Hi!

I'm trying to setup GPU passthrough on my machine. I have 2 GPUs:

04:00.0 VGA compatible controller: NVIDIA Corporation GF116 [GeForce GTX 550 Ti] (rev a1)
        Subsystem: ASUSTeK Computer Inc. Device 83be
        Kernel driver in use: nvidia
--
0c:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6600/6600 XT/6600M] (rev c1)
        Subsystem: Micro-Star International Co., Ltd. [MSI] Device 5021
        Kernel driver in use: amdgpu

I was able to pass AMD gpu to the guest but then nvidia card provided for the host goes black. How I can preserve functionality of nvidia card?
Both cards are in their's own IOMMU group.
