The problem is a bit tall but the top out is safe in my opinion. I didn't use the right arete for the last move to reach the top hold cause I can't reach.

Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
