After the latest update:

1. After starting the cursor IDE if it doesn’t freeze, it either crashes or loads slowly
2. Before, it worked smoothly
3. I am using it on a windows 11
4. Once using it, it is buggy, freezes, slow to upload, delayed response,

Hey, thanks for the report. This is a known issue after the latest update, and the team is aware. It looks very similar to [Cursor is not usable after the last update](https://forum.cursor.com/t/cursor-is-not-usable-after-the-last-update/150165)

A few things to try:

Quick fix (if you need to work right now):

- Roll back to the previous version: [Download · Cursor](https://cursor.com/download)

Workarounds that helped other users:

- Clean reinstall
- Start with `cursor --disable-extensions`. If that helps, it’s likely an extension issue
- If you use MCP tools, try disabling them temporarily

Info needed for debugging:

- What Cursor version are you on?
- If you run without extensions, does the issue still happen?

Let me know what worked, or if nothing helps.
