Sandboxie will not allow any Microsoft program or data logins

URGENT !! This problem needs immediate attention.

My PC is a desktop using Windows 10 version 1903 and Chrome is my
default browser version 76.0.3809.132 - 64 bit.

I recently updated my Windows 10 from version 1809 to 1903. Before that
everything worked perfect. The same with my other browsers - no problems at all.

My Sandboxie is version is 5.31.1 and has been for a few weeks now.

Problem !
All my browsers when sandboxed will not allow any Microsoft login for Outlook.com email,
Skype or any other Microsoft program or data file. This applies to Chrome, Firefox, Opera and Skype.

As soon as a Microsoft login or data entry is needed, the screen greys over and freezes. It then has to be crashed.

This fault is a major disaster and simply must be corrected immediately, otherwise using Sandboxie
becomes a very doubtful proposition.

NOTE - All these browsers etc. work perfectly well unsandboxed - no problems at all.
