Hey, usually clearing the cache or reinstalling Cursor helps, but one user mentioned that this error disappears after some time:

> [@Cursor crashes on startup (A JavaScript error occurred in the main process)](https://forum.cursor.com/t/cursor-crashes-on-startup-a-javascript-error-occurred-in-the-main-process/29215/8):
>
> The same thing happens to me too when opening a big project which causes Cursor to crash. Reopening Cursor afterward brings up this error, and after waiting for a minute, Cursor opens normally, reopening the project that previously crashed without any problems. I didn’t need to reinstall it, and it functions perfectly otherwise-I just run into this issue sometimes.

Reinstalling Cursor should also fix this, according to some users!
