Agents getting stuck on the navmesh

Hi!
I'm encountering an issue with NavMesh in my game. In their "standard" state enemies are supposed to go from a random tile to the other. But, as you can see in the gif, they sometimes get blocked in a random corner. They will leave the corner only if they hear the player (which updated their target). Also, this problem seems to be happening mainly once some of the obstacles have been destroyed (each obstacle has a navmesh obstacle component whith carving activated).

Thanks in advance for any help !

 

Here's the gif :
