Hi, I would like to ask for help.

I have followed the FAQ on Bultibootusb's web. So I have uninstalled the previous version of Multibootusb, installed all dependencies:

Code:
python3-pyqt5
p7zip-full
parted
util-linux
python3-pyudev
mtools
python3-dbus
python3-six
then I downloaded the source code of multibootusb. After I run:

Code:
 sudo python3 ./multibootusb
I get the following error:

Code:
Using python version  3.8.6 (default, Sep 25 2020, 09:36:53)
[GCC 10.2.0] on platform Linux-4.19.128-microsoft-standard-x86_64-with-glibc2.29
Running multibootusb version 9.3.0 from source...
Starting multibootusb GUI...
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
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.

Aborted
Is it because of the plugin, can you please give me some advice what should I do, thank you.
