I remember this as a problem that *some* students had last year but, again, not all students are having it this year. Clearly your DISPLAY variable is set, to :0.0, but that's not the correct value. Reading stackoverflow, again..., there were many suggestions, but some are now 2 years old and don't always work. One frequent suggestion is to set:

 export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0 # in WSL 2
 export LIBGL_ALWAYS_INDIRECT=1

Another says set it with export DISPLAY=$(hostname):0.0 Others now say that DISPLAY should not be set at all - https://superuser.com/questions/1580610/how-to-run-gui-apps-with-windows-subsystem-for-linux No definitive answer.
