Do you have a minute to DM and see if we can figure it out? If not, here are some steps to take:

In Chrome (or any Chromium-based browser) open the Developer tools window (where that is depends on the browser. The pic shows where it's at in Chrome. There will be a bunch of red error lines in there because a lot of Nip05 verification sites reject calls from web apps. Ignore those.

Logout and then back in, and watch the Developer window to see if any red error lines pop up when you do so. If you see any, expand the error line and copy/paste all the information it shows into a response here. That will at least tell me where the issue is coming from.
