Steps to Reproduce:

1. Run CodeSnap to copy an image to the clipboard.
2. Observe the crash.

[mistricky]

I can't reproduce it, CodeSnap works fine with Neovim 0.10 on my Mac, have you tried reinstall CodeSnap and try again?

[try-to-fly]

After debugging, I discovered that this line of code was causing the crash. Commenting out this code prevents the crash. However, when I attempted to update the board to the latest version(v3.4.0), it also crashed. I'm not sure where the problem lies.

Summary

While testing the board module, I encountered errors when executing the demo. After analysis, I found that the issue was caused by the DYLD_LIBRARY_PATH environment variable. Removing this variable resolved the issue.

Detailed Description

Based on the above analysis, I attempted to test the board module and found that executing the demo also resulted in errors. I found a similar issue mentioned in the issues section: https://github.com/1Password/arboard/issues/109

The issue mentioned DYLD_LIBRARY_PATH as a potential cause. I had added this dependency when installing a certain functionality but forgot about it. After removing this environment variable, everything worked fine.

I will continue to investigate why DYLD_LIBRARY_PATH causes the crash.

export DYLD_LIBRARY_PATH="/opt/homebrew/lib/"
