The floor is what material and how thick ?

We may be thinking the same thing. Replace the landing sub floor?

It is cement I guess. Now in that area, Laminate then Vinly (peel and
stick) then cement floor.

It appears that it was poured slab over a crawl space from the video.

Need as somebody else says to

a) determine what the purpose of making the hole in the first place was
b) determine if that reason has either been fixed or remains

That determines whether you actually to retain access permanently or
temporarily

In the end it looks like it should eventually be formed from the bottom
w/ some supporting and probably re-poured. It'll take some sort of
structural work underneath or insert rod or other support by drilling
into current slab (a lot more work in all likelihood) to get something
solid.

Alternatively, again start w/ a support structure underneath and frame
in a short section as if it were regular floor joist at level to support
a subfloor (1" T&G or couple layers 3/4" would be solid enough).

After that you can re-lay flooring to match whatever. But again, it all
needs to start w/ determining the "why" of what went on.

If need be, contact previous owner and see if have any information.

If it's a concealed defect that wasn't revealed you may have recourse in
getting at least some help on repairs if it does turn out to be major
problem underlying that reason and not just repairing the remnants of
the repairs.
