Fresh install - GeoServer will not start

Description

Hi.
This issue has been covered to a certain degree in previous posts but none of them match my environment, so I am hoping someone has half a clue as to what is going on.

The catalina.out logs show a number of errors, such as this one:

My tomcat.service config looks like this:

I have attached my logs for completeness.

If anyone has any info on this, it would be greatly appreciated.

Kind regards,
Neil.
