Are Black screens ok after Anaconda Navigator 3.9 install in Windows

Can you please advise. I was able to install Anaconda Navigator 3.9 in Windows, only black screens first appear and then flash a few seconds on the screen about 3 times, before getting to the Anaconda Navigator. Then the black screens are gone.
Are the black screens okay? Also what do you think is causing these black screens and then flashing 3 times?
Regardless, Anaconda Navigator 3.9 seems to be running fine. I also tried to uninstall and reinstall, and still have the same flashing black screens issue.
