Logged in but can’t get to Dashboard

Hi,
having an odd issue that I’ve never encountered before. I can log in but all I see is live site with black Admin bar up top (same for any user login). If I click site name to get to dashboard it just reloads the website. If I add wp-admin to my url I get “Sorry, you are not allowed to access this page.”

Here’s what I’ve tried so far without any luck (via cPanel):

1. Rename Plugins’ folder.
2. Rename active theme’s folder (twentytwenty is present to default to).
3. Manual update of WordPress core
4. Looked at .htaccess file — nothing weird there.
5. Noted that Admin user privileges were missing in Database so I added that back.
6. Added new Admin user directly into database.
7. I would revert to previous backup, but this is a brand new site that I just started and of course put tons of hours into the design and got locked out without warning or backing up.

I’ve probably tried 10 other things that I came across here on www.ads-software.com but the results are the same — I can log in but not get anywhere beyond the live website.

I’m running out of ideas. Please help me if you can.
