When I install on the Ubuntu 22.04, it crashed. Can anyone let me know what to do next? Thanks in advance

Below is my configuration:

openproject/edition default
postgres/autoinstall install
postgres/db_host 127.0.0.1
postgres/db_port 45432
postgres/db_name openproject
postgres/db_username ************
postgres/db_password nA7xGhx998FwomkdsKnvRgRS8NeHi4NO
server/autoinstall install
server/variant apache2
server/hostname amtx-tick-system.australia-southeast2-a.c.gold-pier-402910.internal
server/server_path_prefix pm.amtxlogistics.com.au
server/ssl yes
server/ssl_cert /etc/ssl/certs/example.com.crt
server/ssl_key /etc/ssl/private/amtxlogstics.com.au.key
server/ssl_ca
repositories/api-key YgQdPjCNp3qDvDVdJFwNDTCnsRPEO9vC
repositories/svn-install skip
repositories/git-install skip
memcached/autoinstall install
openproject/admin_email name@email.com
openproject/default_language en
postgres/addon_version v1

and the output right before the crash.

AH00526: Syntax error on line 2 of /etc/openproject/addons/apache2/includes/vhost/ssl.conf:
SSLCertificateFile: file '/etc/ssl/certs/example.com.crt' does not exist or is empty
Action 'configtest' failed.
The Apache error log may have more information.

Below is the ssl.conf file
