Urgent Help Needed: Lost Access to WordPress Admin and Site Missing

Hello Community,

I’m in a bit of a bind with my WordPress site and could really use some urgent help. Here’s what happened:

1. I usually log in to my WordPress admin via beachcomberdr.com/admin.
2. I recently tried to change my domain name to lascanasbeachretreat.com.
3. During the process, the screen froze, so I had to close the tab.
4. Now, when I try to log back in through beachcomberdr.com/admin, the site takes forever to load and ultimately shows an error message.

But it doesn’t stop there:

1. I can still log in to my WordPress.com account, but my current site, beachcomberdr.com, is not listed. Instead, it’s showing two old sites that we haven’t used in years.
   
2. To make matters worse, I can’t even access the site at beachcomberdr.com anymore. It’s as if it’s vanished.
   
3. The new site I tried to redirect to, lascanasbeachretreat.com, isn’t showing up either.
   

Has anyone faced a situation like this? I’m extremely concerned that I may lose access to my website entirely. Any immediate advice or guidance would be invaluable right now.

Thanks so much for your time and help.
