Why Does Krunker Keep Closing?

Krunker.io is a browser-based game, meaning it relies heavily on your browser performance, internet connection, and system resources. If any of these components fail, the game may crash or close unexpectedly. Below are the most common reasons why Krunker keeps closing:

1. Browser Compatibility Issues

Krunker works best on Google Chrome, Firefox, and Microsoft Edge. If you're using an unsupported browser (like Safari or Opera), the game may crash frequently.

5. Browser Extensions Interference

Some ad-blockers, script blockers, or VPN extensions can interfere with Krunker's functionality, causing it to close unexpectedly.

A corrupted browser cache can lead to game crashes. Clearing cache and cookies often resolves this issue.

7. Server-Side Issues
