Start with the linked crash log and reproduce the failure in Structurize 1.0.788-1.21.1-snapshot on Minecraft 1.21. Test opening and approving with the shape tool, including after moving the shape from its starting position, and compare with the unaffected build tool. Done means these shape-tool actions no longer crash the game.
