Error when deleting user account

Hello,

When trying to delete a user with Users -> Manage (com_users) I get the following error:

An error has occurred.
0 DateTime::setTimezone(): Argument #1 ($timezone) must be of type DateTimeZone, string given

Joomla 5.1.0
PHP 8.1.14
Database 10.4.28-MariaDB
JomSocial 4.9.1

I originally posted on the Joomla forums but they determined the issue is coming from JomSocial?

See the attached photos for the error both with and without debugging turned on.

Any ideas? Thank You!

I can't duplicate this issue at my side, could I take a backup of your site and check in my local environment?

saguaros Yes, go ahead. Akeeba Backup is on my site.

Could you share the correct URL to access backend of your site? I tried with /administrator but it seems not to be the correct one.
