Godot 4.2.2: Area3D cant collide with CSGBoxes or StaticBodies

I am currently trying my hand at a 3D ARPG in Godot 4.2.1 (and 4.2.2) and have a problem with collision detection. The collision between my projectile (Area3D with CollisionShape3D) collides with an enemy (CharacterBody3D) as expected, but not with instances of StaticBody3D or CSGBox3D. Setup:

• Collision Layer and Mask on Projectile and all Targets set to 1
• body entered and area entered signals on the projectile are connected to respective functions in the script projectiles script
• Monitoring is enabled

I am wondering if the problem is that the projectile is an Area3D? Or am I missing something obvious?

Thanks in advance.

What i tried:

• changing collision layers and masks
• changing the speed of the projectile to a stupendously low value
• changing the root node of the projectile to a RigidBody3D (resulted in no collision at all, not even with the enemy

I found out what the problem is: I was using jolt. When switching back to the default physic engine, everything works like a charm. Jolt seems to be broken in other areas at the moment (at least for 4.2.1 and 4.2.2), or I just dont handle it right. Another big issue is, that the game just crashes without any hint, when there are runtime error in my scripts. Since I only just started with GDScript, that happened a few times and left me baffled...
