Logging into WordPress Admin Dashboard is working as expected using the native WordPress login functionality, e.g.
https://example.com/wp-admin - Website is using PHP 8.x version
Cause
Elementor plugin bug.
Resolution
Contact Elementor plugin Support to address this issue.
While the issue is not fixed by the vendor, here are some possible workarounds:
- Switch the website to an older PHP version (e.g PHP 7.x)
- Login to WordPress through the Subscriptions Screen (using the Active List rather than Dynamic List view

It appears that this issue has resurfaced...
Another workaround is to go through the subscriptions screen (active list NOT dynamic list, as that is broken as well).
Confirmed for newest version of WP, Plesk (on Ubuntu 22.04), and Elementor (v. 3.16.3 and Pro v. 3.16.1 and all 3.15 versions), and PHP 8.2.
It SEEMS like this issue is Elementor but ALSO is Plesk, since it works using different methods INSIDE Plesk as demoed in this video about the new forcing of Dynamic lists:

I can confirm what Unknown User found out. Login in via Active List works fine. So strange!
