New unexpected OS pending updates caused this Catastrophic failure while Cursor was running.
Fixed the issue after rebooting the machine.

This error indicates that there was an error connecting to WSL. You will need to either shutdown wsl (wsl --shutdown) or reboot your computer.
When will your web site be back online so we can get to our invoices etc! Thanks P
