Copy by Reference suddenly stopped working

The problem: Copy by Reference has stopped working starting today, the last time the function was still working is yesterday.

There is still a success prompt after trigger by either context menu button or shortcut.

I checked the Clipboard Manager and can confirm only Copy by Reference is indeed not working, whereas Copy by Clone is working fine.

What I’m trying to achieve:
Copy the URL of MN3 note in Mindmap.

What I’ve tried, by order:

  • Restarted MN3
  • Restarted computer
  • Disabled all extensions
  • Clear Temp Storage
  • Database Defragmentation
  • Uninstall & Install MN3 again

Please help look into this issue and suggest a solution or a workaround.

OS: macOS Big Sur 11.4 Apple Silicon
