Hi,
I assume it is the Minecraft Launcher stuck at 73 or 80? Or the game itself in the Launcher?
Sometimes it may appeatr stuck, but it is doing the backend work. In that case switching is recommended.
Try this direct download link which should work:

I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!
