When try to open the site I got the error message above. I reinstall the bench but same message again. Update also no help. Here is detail. What should I do?

Traceback (most recent call last):

are you update erpnext develop or production?
if you use erpnext production, before you update, switch-to-master first

frappe-bench$ bench switch-to-master
frappe-bench$ bench update

if, you get error again
try this.
frappe-bench$ bench remove-from-installed-apps ldap
frappe-bench$ bench migrate

Thank You komsel2228,
I have already deleted all the folders including frappe bench, removed all users in MariaDB database and installed it again. However, thank you very much for the help.
