Player getting stuck at blender mesh collision

Godot Version

v4.3.stable.official [77dcf97d8]

Question

My Player that uses a CollisionShape3D with an CapsuleShape for colliding keeps getting stuck at the wall of my Blender Model. This Model uses an ConcavePolygonShape and is just a square out of meshes at all sides (no special form rotation etc.) The Player can’t move in ANY direction after getting stuck. Additionally the property is_on_wall is false most of the time when the player gets stuck.

Things I tried already:

  • Making the Player motion mode float
  • Changing the physics Engine to Godot or Jolt Physics
  • Exporting the blender model as .glb file
  • Applying the root Scale in import settings
  • Enabling physics Interpolation

Is this an already known issue with Godot 3D or did I make a mistake anywhere?

Feel free to ask for more information/pictures if needed.
