Error running Atom Ubuntu on WSL

I am trying to run the Atom editor in Ubuntu 20.04 under Windows Subsystem for Linux.

I installed Ubuntu then Node.js. Both seem to work fine. Then I followed the instructions on this site for installing Atom.

When I then run atom, I get the following:

ro@PC:~$ atomexpr: syntax error: missing argument after ‘8’ro@PC:~$ /usr/bin/atom: line 195:    89 Segmentation fault      nohup "$ATOM_PATH" --executed-from="$(pwd)" --pid=$$ "$@" > "$ATOM_HOME/nohup.out" 2>&1

This is what is in my ~/.atom folder:

ro@PC:~/.atom$ lltotal 8drwxr-xr-x 2 ro ro 4096 Apr 25 09:52 ./drwxr-xr-x 9 ro ro 4096 Apr 25 09:52 ../-rw-r--r-- 1 ro ro    0 Apr 25 11:52 nohup.out

I have no idea what I am doing wrong as I am new to Linux.
