Unable to launch Galaxy on Windows using WSL

I am trying to run Galaxy on Windows using WSL which is installed with Ubuntu 22.04.
While following the steps to install Galaxy here, I face the error

Activating virtualenv at .venv
ERROR: A virtualenv cannot be found. Please create a virtualenv in .venv, or activate one.

when trying to run the line GALAXY_CLIENT_SKIP_BUILD=1 sh run.sh.
Can someone tell me where I’m going wrong ?
I’ve attached a screenshot for reference…
