Server Errror 500 after upgrading v.2.0.1

Recently I’ve upgraded my cyberpanel to version 2.0.1. After that I cannot login to cyberpanel dashboard. It told me “Server Error (500)”
I’ve changed the password of user ‘cyberpanel’ and updated in /usr/local/CyberCP/CyberCP/settings.py but no luck.

Here is output of “journalctl -xe”, please help me:

I tried to upgrade again with version 2.0.1 after update cyberpanel user’s password but it was still error 500.

last log after upgrade below:

the mariadb is still running in old version, but I cannot upgrade from v.10.0.38 to 10.1.45. Only cyberpanel dashboard cannot accessed, my websites are still running.

reboot vps & restart lscpd, still failed with below log:
