NBT tags fail to parse correctly

Bug Report Summary (Java 1.21.9 Snapshot 25w31a):

Title:
"Game crash when clicking NBT-copied blocks (e.g. lectern with book) in GUI interfaces"

Steps to Reproduce:

1. Launch game (Version: 25w31a).

2. Place a lectern and insert any book (text optional).

3. Ctrl + Middle-click to copy the lectern (now with NBT data).

4. Open any GUI (e.g. chest).

5. Click the NBT-copied lectern in the GUI.

6. Result: 1-3秒 freeze → Crash to desktop.

Affected Blocks:

• Lecterns (with books)

• Chiseled bookshelves

• Signs

• Item frames

• All NBT-copied blocks when interacted via GUI.

Technical Note:
Likely caused by improper NBT data handling during GUI item slot interactions.
