Thanks for the info. Just to close out the thread, I found another post that implied that it might be hard drive failure that causes this issue, so decided to check it out.

I removed my hard drive (and made a how-to video
), and found that though the navigation didn't show back up, the boot loop stopped happening.

I was then able to follow this thread on e90 post to upgrade my drive to an SSD, resolving the problem:

Hope this helps someone!
