Yes! If you wait a few hours and update it should be fixed - we are pushing out a TaxYear 18 update with a fix for that today.

Alternatively you can apply the fix for TY18 manually by following the steps here: https://proconnect.intuit.com/community/manage-access/help/manage-users-sign-in-screen-is-blank/00/5...

(Today's update will just do that automatically)

If you're wondering, that login dialog is a web thing hosted in a small version of Chrome we include.  It has an issue with Microsoft technology that you're running into.. I see it on my HP Envy with intel iRISxE Graphics Card.  This fix switches back to the older internet explorer component used by TaxYear 17 and older.  In the summer, we're hoping to move everything to Microsoft's newer component once they release it.
