Gazebo does not launch ([RenderEngine.cc:749] Can't open display)

I try to use gazebo or gazebo with ROS noetic in WSL2 (Ubuntu 20.04.2 LTS, Windows 10) using VcWsrv. However, during launching Gazebo gazebo --verbose I got errors:

[Msg] Could not load the Qt platform plugin "xcb" in "" even though it was found.
[Err] [GuiIface.cc:124] This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

VcWsrv was adjusted in accordance with the following video: https://www.youtube.com/watch?v=DW7l9... I found mention (https://stackoverflow.com/questions/29405689/qt-5-4-1-this-application-failed-to-start-because-it-could-not-find-or-load-th) about path changing to Qt, but I don't know how to find path to Qt and where I should change it.

If I use command roslaunch gazebo_ros empty_world.launch, I get th following error:

I spent several days to search solution, but it didn't help me. Could anyone help me with it?
