Can you pull the curved top trim off, it will break and you’ll need to put a new replacement up but maybe the new one going back could be in one piece.
Good luck

Ps I saw the tape in the wheel barrow and thought 5cm, that’s not much. 5” yeah, no thanks.
The masonry veneer was applied after the windows were installed, but that top trim section is just a piece of pvc board nailed on above. One way or another It should come out without too much difficulty.
It's been a wet summer, but 5" is unusual.
