Ok looks i’ve found the culprit!!
I lowered the damage threshold to be able to break it with the simple attack (500), only that when the anchor is inserted, the geometry collection requires an impulse to activate and at that point the strength of the latter was so strong (10,000)that the hurled objects, smashed everything around them.
Fixed by raising the damage threshold to the standard level (500k) and raising the pulse to 510k is enough to destroy the nearby crate but not so strong as to break the rest
