Okay I'll cut you some slack and explain it more clearly - the "undisarmable undestroyable trap" concept is not something that first appeared in bg3. It was in dos2 as well. So I don't think it's a bug, but an intentional design choice, a very poor one.

Larian's Biggest Oversight, what to do about it, and My personal review of BG3 EA
"74.85% of you stood with the Tieflings, and 25.15% of you sided with Minthara. Good outweighs evil, it seems."
