There are threaded inserts in the screw holes and it looks like you used (way) too much force and got the inserts stuck to the screws. In your second picture you can clearly see the threaded inserts stuck to screws 1,3 and 4 and on the first picture you can see the threaded insert missing from the screw hole.
Maybe you can remove the inserts from the screws and glue them back in the holes, but you’ll probably need very good glue.
