SharePoint Designer login & Office 365 site - MFA - site does not open

Brass Contributor


I have an issue when opening an Office 365  SharePoint site with SharePoint Designer. The MFA process starts, ask to confirm on my phone and I can enter the number I receive. And then I receive a message box telling me "An error has occured in the script on this page" - "The data area passed to a system call is too small" - url ""


Continue "Yes" or "No" does not make a difference, the site does not open :(  Any ideas ?


Thank you,
