Hi
this means that your MFA method has failed or is not valid. Details in this thread:
https://learn.microsoft.com/en-us/answers/questions/963875/error-code-500121-business-central.html
You'll need your company admin to reset your MFA methods to allow you to set these up again.
Hope this helps,
Thanks
