Accessing my Ubuntu 1804 through rdp

I am trying to access my Ubuntu 18.04.6 LTS from a windows 10 machine using xrdp. Just after I installed xrdp on my Ubuntu, it did work once. But I get a blue screen on my windows machine ever since.

• I searched on google with the terms another Xserver might already be active on display 10 but none of the solution did work for me.
