Screen Flash, Monitor not working

[ptitt0m]

Hello,

Since i have Catalina, i have a issue. There is no way to use my universal dock D6000 with two monitors and my macbook pro.
I downloaded the last software but when i plug my dock, the screen of my mac is flashing and the monitor just stay black. And when the screen is flashing there is no way to use the laptop.

I dont know what to do because i need this two monitors for work.

Thanks you
