RStudio server fails to connect after reinstallation with System Error 2

RStudio IDE

Hi all,

I recently reinstalled rstudio-server (2024.04.2-764-amd64.deb) to get the latest version on our Ubuntu server (V. 20.04).
Attempting to connect on a browser with "http://serverSSH:8787/" results in an HTTP ERROR 503.
Using sudo to check the server status shows this error:

Any help on getting this fixed is much appreciated! Please let me know if any more information is needed.
