SuiteCRM 8.1 Ubuntu server 20.04 PHP Fatal error: Uncaught Error and the web interface is missing the top bar

On fresh install on Ubuntu server 20.04 the SuiteCRM 8.1 returns PHP Fatal error: Uncaught Error.

The forum does not allow to paste a lot of characters in this post. I had to share it through Dropbox

access.log
error.log
install.log
suitecrm.log

Environment:
Ubuntu server 20.04
PHP 8.0.17
MYSQL 8.0.28
Apache 2.4

Any help to resove this issue would be apreciated. Thanks.
