Help! How do I delete blueprint that’s unreachable in multiplayer mode?

Made a very silly mistake today

I was exploring cultist cave with my fiends. While waiting for them to climb up the rope I was messing around and added some blueprints on the wall of the structure. Realized I can’t reach them to cancel it afterwards. Now there are 800 logs and a whole bunch of materials taking up my screen when I’m outside of the cave😭😭😭

I saw there are someone changing some files in a game folder and did it but the file appears different in multiplayer saving file…
