# `platform.check_failed`: The check itself failed

A build check error in the area "The platform". An error: the game cannot be published until it is fixed.

The build check runs on every game LobbyLab builds, and each problem it finds has a stable code, the exact message, the file and line when it names one, and a link to this page.

## What the check looks at

Problems of the check itself, not of the game.

## How to fix it

Run the check again in a minute. If it still fails, tell us through https://lobbylab.gg/support.
