Generating License File on the Steinberg Activation Manager Doesn't Work for Some Unexplained Reason

I followed as the steps as pointed out in this video

The reason why I am using offline activation is the Steinberg Activation Manager is faulty; it doesnt open a log in on my browser, keeps crashing, causing freezes at the splash screen. I haven’t been able to log in for 2 days.
Windows 10

Any help would be much appreciated
