Hello. Could you take a photo of the HAT?

Hi! I won't be able to until tonight but here's the exact model I purchased:

Geekworm KVM-A3 Kit with Raspberry Pi 4 Case Compatible with PiKVM ATX HDMI CSI for Raspberry Pi 4 Model B Only(Not Include Raspberry Pi)

https://www.amazon.com/dp/B0B5R37TT3

I have the latest updates and I installed NeoVim, just a heads up in case that's causing any conflicts.

Sorry, but this is not a compatible device, and we don't support it. We support either DIY or V3+ devices. You need to contact the manufacturer.
