What causes this Sign-In Error?

Ways to Fix the We Can’t Sign Into Your Account Issue

If you made any changes or created any files while logged in to the temporary account, they will be lost upon signing out. So, please save the files to an external storage device if necessary. Then, move on to the solutions listed below.

Restart your Device

The error prompt advises that “signing out and signing back in” often resolves this issue. Honestly, it’s unlikely that this will help, but it doesn’t hurt to try this a couple of times anyway.What is, instead, very likely to help, is restarting your device. We recommend that you first restart and boot into safe mode and check if you can sign in with your original profile. If that doesn’t work, you should boot normally and try to sign in to the original profile once again.Note that it’s worth restarting multiple times as this has fixed this issue for many users.

Disable Security Services

If restarting didn’t help, you should ensure that a security service isn’t interfering with the sign-in process. Avast, for instance, has caused login/profile issues in the past.If you’re using an older antivirus, you should first try updating it, as issues like this usually get patched in the newer versions. Next, try disabling it temporarily. If the antivirus turns out to be the culprit, you should consider switching to a different antivirus, or Windows Defender.Speaking of Windows Defender, you should also disable some Windows Defender services temporarily to make sure they’re not causing this issue. Here are the steps to do so:
