Windows Defender is not allowing to upgrade App version to 5.15.7

Hello,
I have a system with Windows 10 Enterprise Build 1903. The app version 5.15.5 is installed in the system. I see the version 5.15.7 released and tried to upgrade. Windows defender is not allowing to run the application and detecting it as a threat.

Please help me out.

To dismiss the warning, click More Info and then Run anyway.

For more information, please see:

I have tried the option, but there is no Run anyways button. I am the admin of the system, but it is still giving me any option to run. I have also tried as Run as Administrator.

Sorry, I do not know why you do not get that option.

See how the window looks on our systems.

Anyway, we have just released 5.15.9 that is temporarily signed with the old certificate, until this gets resolved.
