Fixing the issue:
Directory '/run/screen' must have mode 777.
This appeared to be caused by screen being installed against
sudo and not the current user's group/s.
It turns out the best way to fix this is simply reinstall screen on Ubuntu WSL (Windows Linux Subsystem) as below:
sudo apt-get --reinstall install screen
This blog suggested this fix which worked perfectly.
Before this, I tried to make this folder executable and a bunch of other things that did not work. Running screen as
sudo did work but this is not ideal.
