Hello,
Your question is extremely confusing.
Is this about Windows log in, or about Microsoft Teams app log in, since you chose the Microsoft Teams category for your question.
Is this your personal computer, or a work/school assigned computer? Are you using a personal Microsoft account to sign into Windows, or a work/school account to sign into Windows?
Can you hold down Windows +R keys, type in netplwiz and press enter, tell me if it allows you to launch it.
