It just keeps loading. Maybe is a problem with the add-on AdGuard? How can I solve this?

Edit: I haven’t solved the problem, but after some time trying some things here and there, I think I know what’s the issue. I have both Chrome and Firefox installed. I was using Lemmy on Chrome, so I tried to login in Firefox, and the issue started. I logged out on Chrome, and tried here on Firefox, everything fixed. TLDR: you can’t have the same account logged in on both Chrome and Firefox.
