Kernel panic when connecting DELL TB16 dock

I am having issues figuring out the why this is happening. My laptop has an usb-c charging/display port, but no thunderbolt, but the dock still works for a while and I can use the ethernet connection and external displays. I`ve updated the BIOS and my system, but still no luck. Any help is appreciated, thanks!
