Help me untangle my 3d printer filament

I have probably a 1/4 of a roll of filament that slid off a roll when I swapped it between a Bambu reusable spool holder. It's been on my floor for a couple months and I have not found any way of getting this back onto a spool, either by trial and error or by finding a good resource online.

All the videos I see are people with tangles on spools, and this would be nice if I was in this situation but I am not.

Any time I try to do this it's just so challenging to get any sort of rhythm or easy process with our ruining the entire thing.

Any advice?
