Hey, thanks for the report. From the screenshot, this looks like an error on the cursor.com website in your browser, not the Cursor desktop app. That Something went wrong screen shows up on the website. Good news, your account is fine, it’s just a page rendering issue.
This usually happens when auto-translate is enabled in the browser, like Google Translate. It changes the page content and breaks rendering. Please try this:
In Chrome, click the translate icon in the address bar and select Never translate this site, or turn off auto-translate, then reload cursor.com.
If that doesn’t help, open the site in Incognito mode or clear your browser cache.
If you actually mean the Cursor desktop app won’t open, not the website, please send a screenshot of the app window and the version from Help > About. Let me know what worked.
