Hello @mrdurham!
Thank you for the extra details and help getting your site over in our messaging. I’m responding back here in the public thread since we may have found a fix for this.
It looks like your Salts are below the Stop Editing line in wp-config.php which we saw cause similar issues a couple of releases ago. We fixed this in the latest release but if you started building this site earlier then the fix wouldn’t retroactively update this so it will have to be done manually.
If you open your wp-config.php file in a text editor and move your salts above the line that says That's all, stop editing! save the changes and restart your site that should resolve the issue.
Here is what your wp-config looks like for example:
Here is what mine looks like on a new sample site:
To reiterate the fix will just be to move those salts up, save, restart the site (Stop/Start) and then you should be good!
