If you encounter the same thing in the future, you can try logging into your Online account using a private or Incognito window. This helps you rule out any browser related issues. Then, try updating the Account and Settings again.
If it works, you can clear your browser's cache to remove the temporary files. You can also use a different supported browser.
I found a helpful article for your reference if you need to update your company settings: Change company name, address, email address, EIN, and privacy settings.
You can always visit the Community if you need anything else. I'd be glad to help.
