Issue Dovecot service(pop3-login) keeps crashing

[a.sari]

I have an issue that my dovecot service keeps crashing it does startup again.
So far what I 've done is that I fully removed dovecot and installed it again (with fresh configuration I deleted /etc/dovecot folder) but the issue remains.
Here is the mail.err log:

Any idea on what is the issue? Plesk is running on ubuntu 18, plesk version: Obsidian 18.0.52

Sadly plesk does not support ubuntu 18, and as my server is out of date, I cannot open a support ticket.
Any other way to get support?
