hi @Pradeep_Kumar and thank you for your post.

Could you try following:

  1. In Cursor, disable all other VS Code extensions for that workspace and restart the app.
  2. Update the Anypoint Code Builder extensions to the latest version and wait for all Mule/ACB dependencies to finish installing.
  3. Open the ACB Output/Problems panels and fix any missing‑dependency or loading errors they report.
  4. For large Mule projects, prefer editing the XML source and only open the Canvas when necessary.
  5. Try the same project in vanilla VS Code with ACB; if Canvas is also slow there, it’s an ACB performance issue, not specific to Cursor.

Which Cursor version are you using and which version of this extension do you have installed?
