After importing my users to a clean installation of Joomla 4.x, I get 500 errors when entering user management, and also in global settings.
In the log it reads:
PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 262144 bytes) in /.../libraries/src/Helper/UserGroupsHelper.php

what could it be due to?

I found the bug. In the _usergroups table, Public had changed its parent_id to 1 (instead of 0). There was also an empty record, with only id. Something went wrong with the import
