Kde not booting up with ts4 dock pluged in

I am using cachyos on lenovo yoga pro 9i with nvidia gpu. If i have calldigit ts4 dock pluged in i see chachy logo, all 3 of my screens get turned on and right before login screen should apear it gets stuck on black screen with loading circle on all 3 monitors.
I also cannot boot into live cachyos kde plasma from usb if i have dock pluged in. It works fine on gnome but i would prefer kde, but i kinda dont want to unplug dock every time i want to boot up pc and then plug it back in.

I have figured out that its the display managers fault. if i switch to gnome display manager it works. any idea how to fix default one?
