This systemd killed by xclock Can't open display: :0 how to remove it?

[tadam98]

Folowing the script by x-apps stopped working.
How can the script be removed?

It can be commented in /etc/bash.bahrc

# System-wide .bashrc file for interactive bash(1) shells.

# Start or enter a PID namespace in WSL2
# source /usr/sbin/start-systemd-namespace <<== comment

either edit with vim or nano
comment it out like stated or rm -rf file_name if it's a single file and you don't have any useful code in there besides that.
