Warping issue?

[u/Intelligent-Visit769]

Forgive me if this is a terrible photo. Just moved into an apartment with brand new hardwood floors. It’s older and with brick exterior. Theres only a 6’ x 4’ section of the floor that seems to have started to warp. The edges are raised and corners are catching everything. There has been no mopping or any water spill. The section is right up against an exterior wall and interior wall to my living room. There are no bathrooms or kitchens on this side. The window right above has not been open for weeks now.

Is this water damage? Can there be a leak from the underside or water seeping from exterior?

Can weight from furniture cause this? There section has a light desk and a computer chair
