Having issues with SPFx isolation build lately

Hello

We have a customer using an isolation version of our product and when we built a new version last week, it stopped working with below error. Unfortunately, once we install the new build, replacing with the older ones that used to work stopped working and showing the same error.

"authorize:90 Unsafe attempt to initiate navigation for frame with origin 'https://xxxx.sharepoint.com' from frame with URL 'https://login.microsoftonline.com/..........'. The frame attempting navigation of the top-level window is sandboxed, but the flag of 'allow-top-navigation' or 'allow-top-navigation-by-user-activation' is not set"

We would really appreciate how to handle these errors. 

Thanks

Vijay
