Please could you show the non-truncated version of that error message? Try this:

journalctl -eu snmp_exporter --no-pager

Also, the error you get from the dry-run is different:

level=error ts=2020-07-29T10:24:35.521Z caller=main.go:156 msg="Error parsing config file" err="open /usr/local/snmp_exporter/snmp_exporter/snmp.yml: not a directory"

This one seems to suggest you're giving the wrong path. Are you sure /snmp_exporter/ should occur twice in the path? What happens if you simply 'cat' the file:
