Can't save a new file with frames in Figma

Hi guys,
I am new so I tried to copy another design and now have the original and the copy I worked on in one frame in one figma file. I wanted to save it as a local copy but when I click to save I see it goes nowhere and a very quick message below says downloading…but nothing else happens.

So I can’t seem to save my file anywhere at all.

Is this a bug?

Thank you.
