Screws stuck inside handlebar – help! aeroad

For no reason whatsoever, both screws holding the Canyon frontlight/garmin mount cracked during a ride. Garmin fell and is damaged but it’s a different story. My main concern is the 2 screws that are still stuck inside the housing.
I have no idea as to how to take them out, and if it’s even possible.
The only thing I can think of is to drill through them.
Have you guys had this experience? Any other ideas? Is it even repairable?
Thanks a lot!
