Upgrading to the latest version of Sanity may fix a desk crash issue when deleting a single item from a gallery.

This sounds frustrating! While your gallery schema looks perfectly fine, Studio crashes when deleting array items (especially images) can happen for a few reasons. Let me walk you through the most common causes and solutions:

Most Common Causes:

1. Outdated Studio version - Array handling has had several bug fixes across Studio versions. Make sure you're running the latest version of the sanity package:

   npm update sanity

   Then restart your dev server.

2. Browser cache/state corruption - Sometimes Studio's local state gets corrupted:

   • Hard refresh (Cmd/Ctrl + Shift + R)
   • Clear browser cache and local storage for your Studio URL
   • Try in an incognito/private window

3. Invalid metadata configuration - If you've customized your image field with metadata options, check your configuration. According to the image metadata documentation, the valid options for the options.metadata array are: image, exif, location, lqip, blurhash, and palette.

   Note that dimensions, hasAlpha, and isOpaque are always included automatically and should NOT be added to the metadata array - including them will throw an error. Make sure your schema doesn't look like this:

   // ❌ INCORRECT - will cause errors
   {
     name: "gallery",
     type: "array",
     of: [{
       type: "image",
       options: {
         metadata: ['dimensions', 'isOpaque'] // Don't do this!
       }
     }]
   }

4. Plugin conflicts - If you have custom plugins or older third-party plugins, they may not handle array mutations properly. Try temporarily disabling plugins to isolate the issue.

Debugging Steps:

1. Open your browser console (F12) when the crash happens - look for error messages or stack traces
2. Check your terminal where Studio is running for server-side errors
3. Create a minimal test document with just that gallery field to see if it's schema-specific

Temporary Workaround:

Instead of using the bin icon, try:

• Click "Edit" on the array item, then use the item menu to delete
• Use the array's three-dot menu to manage items
• Manually edit the document JSON in Vision plugin as a last resort

If none of this helps, the browser console error message will be crucial for diagnosing the issue. Post it in the Sanity Slack community or search GitHub issues - the team is very responsive to crash reports and may have a specific fix for your Studio version.
