Research direction
Investigate the git diff viewer component in VS Code, likely in the 'src/vs/workbench/contrib/git' directory. The issue occurs when staging a PNG file and opening it in the diff viewer, which errors out. Look for image handling code in the diff editor, possibly in 'vs/workbench/contrib/git/browser/gitDiffEditor.ts' or similar. Check recent changes to image rendering or git diff logic. The screenshot shows an error, so replicate the error and trace the code path.
