500 error on admin page after upgrade

Hello - I cannot access /admin - and am getting a 500 error. It appears to by python related - I’ve tried re-running mailinabox, there are no errors. Will keep working on this, but wondered if the community had any suggestions.

/mail works fine, /admin/munin works fine, and all other functions of the box work fine.

This appears to be the error issue in syslog:

In the end, I couldn’t solve this, so instead simply spun up a new server using backups, and all is good.
