Thank you for the photos and videos.Thanks for all of your help, these photos are not easy to take by myself so hopefully they're at least any amount of useful for you
I have looked through each photo and the video, and nothing is jumping out at me. I'm going to tag a couple of other folks that might be able to help. I don't think you're dealing with bumblefoot, but did you check to see if there was anything obvious on her foot or leg that she might have stepped on, something sharp?
She might have simply pulled a muscle or bumped into something, maybe even bruised the leg jumping up or down from roost bars - it DOES happen. Shezadandy gave some good advice above about isolating her in a small area like a dog crate for a few days where she can be monitored and where she is can't jump up or down so that she can rest without strain.
The leg scales don't look too concerning to me, but the angle of the photo is not great - I know it's VERY hard to hold a bird AND take photos! Let's see if these folks can't shed some light on why your bird might be walking with a limp:
