cursor The window is not responding when open cursor,

When I use Cursor to open a project on WSL, I encounter the issue where "The window is not responding." Subsequently, I attempted to install the latest version (0.42.3), but the problem persists. Opening Cursor is very slow, and it also consumes a high amount of memory(at least 4GB.).

Same problem. Many people have had the same problem. It seems to be a memory consumption issue. I am currently paying for the service and I am not able to use it.

Same here. On Mac OS. 8GB Mac mini M1. I tried opening the project in vscode, running it and the going back to cursor. At least I get the prompt back. It can be a fix if you need disable some things, but I am back with vscode until this gets fixed. Cant afford these scares.

same but just for some project. the other project is fine

Same here

Mac M2 Pro 15.3.1 32 GB

My sense is it's around the loading chat history - if I clone a fresh instance of my repo it opens just fine (though I've lost the chat history)

I was able to fix this by opening the problematic project with another IDE (Pycharm, in my case,) committing my Git changes, closing the IDE, and reopening Cursor.

Open project in another IDE (pycharm)
git add .
git add -u
git commit -m "ahhhh"
Close IDE (pycharm)
Reopen Cursor

I was also able to get around this by just deleting my existing repo and re-cloning

Just buying clearing cache helps. To clear Cursor AI's cache on your Mac, you can remove its associated data and configuration files. Here's how to do it:

Close Cursor AI: Ensure the application is not running. Open Terminal: You can find Terminal in the Applications > Utilities folder. Execute the following commands to delete Cursor AI's data:

rm -rf ~/Library/Application\ Support/Cursor
rm -rf ~/.cursor*

The first command removes the main application support files. The second command deletes any hidden configuration files related to Cursor AI in your home directory. These steps ensure that all settings and extensions are removed, providing a clean slate for Cursor AI. Restart Cursor AI: Upon reopening the application, it will recreate the necessary files with default settings.

是对话的缓存文件引起的卡住，win10下删除 %APPDATA%\Cursor\CachedData 文件夹即可，就是历史记录都没了 It is caused by the cache of chat. You can fix it by removing %APPDATA%\Cursor\CachedData on win10

my advice how i made it work again : delete the whole cursor cashe on your device

follow instructions on google for this.

delete cache restart cursor login again

note: if you delete all of the cache some of your personalised settings might be gone

For windows close cursor. Clear AppData folders:

Press Windows + R, type %APPDATA% and hit Enter Find and delete the Cursor folder if it exists Press Windows + R again, type %LOCALAPPDATA% and hit Enter Delete the Cursor folder here as well if present

Clear temp files:

Press Windows + R, type %TEMP% and hit Enter Remove any Cursor-related temporary files

Getting the same problem. Cursor has a HUGE MRR, yet it's riddled with bugs. Can't wait to cancel my subscription.

Had the same problem on Windows 11 in one of my projects. I tried removing the %APPDATA%\Cursor\CachedData folder and all other sibling folders with cache in the name, but it didn't help. Ultimately, I had to remove the whole %APPDATA%\Cursor folder, which fixed the problem. But unfortunately, this means I had to log in again and adjust my settings again. I really wish Cursor supported cloud sync for the settings.

The project lives on a remote server, and I'm using Remote-SSH to access it, if this makes any difference.

This same problem happened again on another machine. This time on Windows 10.

This time I was able to fix the problem! 🎉 I located the project's chat history in %APPDATA%\Cursor\User\workspaceStorage\<workspace_id>, and removed that folder. The project's history is gone, but this didn't affect any other projects.

I was able to find the correct workspace_id by searching for my project's name in the workspace.json files.
