Working Okta App Sudden Logout/Login Fail in Safari

To context for this is that we are developing an application in Vue that Okta Authentication has been working just fine in for months. Apparently after upgrading from Safari 13.05 to Safari 13.1, I have a user who can no longer logout/login of the application. It fails on the Okta URL callback.

MacOS 10.15.3
Safari 13.1

Has anyone else experienced this? If so, is there a patch in the works?
