Cannot log on to OneDrive with Work & School account

[AtanasM]

I cannot sign in to OneDrive desktop app on PC with business account. It seems, that the personal Microsoft account is automatically used. The issue don't exist in OneDrive web app.
Error message: In the script on this site occurred an error. URL: https://account.microsoft.com/family/child-consent/....
After clicking on "Run script" button there appears a new window prompting for parent approval.

Deleted already all related sign in info in Credential Manager.
OneDrive Reset.
Tried to run OneDrive as administrator, but it was not possible.

@AtanasM Same here!
