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

Hi,

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 "https://login.microsoftonline.com/common/SAS/ProcessAuth"

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

Thank you,

Marc
