If it's got an accessible screw/fixing holding it in place from the inside, or on the edge where the locking action happens, back that off a bit and give it a squirt of something oily.

If this is an outward opening window, where shoot bolts extend into the frame keeps, it's probably a gearbox similar to this (maybe even the same) and one side fucked or the rod has detached.
https://jcphardware.co.uk/saracen-shootbolt-gearbox-upvc-window-lock/Theres two screws holding the handle to the gearbox and thus the gearbox located within the window.
With he handle in the unlock position, remove screws and then try persuading the gearbox away from the stuck side. If your lucky the gearbox cutout is big enough for that to work.
If it's a reasonably large (bendy) window, pushing the free side outwards to clear the keep and usung a wide stiff scraper you can lever the stuck side free.If you have another window the same, get some pics and I'll have a look

The locking bars within one of our double glazed windows has jammed in place - bottom left corner.
The other pins will shift to the unlocked position, but even after some light percussive maintenance the bottom left won't shift. How to make fix?
