Error: ERROR REQUESTING Token FROM THE Authentication context - Error: Path cannot be the empty string or all whitespace.

Trying to connect XrmToolBox v.1.2019.11.35 to Dynamics 365 using a user account with MFA. Can't use app passwords because they aren't compatible with Azure AD Conditional Access.

When I use the Connection wizard with CRM online option I get the following error messages:

I also tried connecting using the Connection string method and got a different error message so I created a different issue for that.

Any help with this error would be greatly appreciated.

Thank you, Matt
