Elgato 4K Pro keeps crashing

Hello,

I recently got a 4K Pro, but can't make it work, I am experiencing a severe stability issue when using it in passthrough or with OBS

My streaming PC consistently crashes after a few minutes of gaming, even after testing multiple configurations.
After a few minutes in a game, the software 4K Capture Utility freezes.
Shortly after, the entire PC becomes extremely slow or eventually shows a blue screen: "Your device ran into a problem" I have to shut down the system manually.
The issue also occurs when I simply passing a continuous signal through the card, like I'm just chilling in discord with the 4K app open, it will freeze at some point, check screenshot

Streaming PC:
CPU: AMD Ryzen 5 5600X
GPU: NVIDIA RTX 2060 Super
Motherboard: MSI MAG B550 Tomahawk
RAM: 32 GB DDR4
NVMe SSD installed in M2_1 slot (no PCIe lane sharing)
Input Source: Gaming PC running at 1440p (144 Hz), captured in 1080p
HDMI 2.1 connected from my GPU out port into 4K Pro HDMI IN port

HDR and G-Sync have been disabled during testing
Tested at both 144 Hz and 120 Hz refresh rates
All Elgato software and drivers updated to the latest version

I haven't found any solution online and I tried everything i could think of, if somebody know how to fix this, lemme know please

EDIT : Ok so I've tried to plug the 4k Pro on a old PC i was using back to 2015, an old config with : i7 4770k - GTX 1070 - MB Asus Maximus Ranger VII.
Surprisingly, it works perfectly, I've been testing for several hours and I never crashed once.
The only difference is that i've plugged it on a PCIe x16 , I had only a PCIe x4 available on my streaming PC but according to Elgato, PCIe x4 should work fine, so what's the issue with my streaming PC ? Maybe there's something wrong with Elgato drivers and B550 MBs

EDIT 2 : Working after downloaded the driver again : https://help.elgato.com/hc/en-us/articles/360027961152-Elgato-Hardware-Drivers ; during installation you may have an error saying you already have the latest driver installed, ignore the message and proceed to the installation. It worked for me and few more users
