Android 4.4.2 is an extremely old operating system (released in 2013). Most modern applications, including the official WhatsApp and its mods, have dropped support for it.
The most critical concern, however, is security. Because GB WhatsApp is a modified version of the original code, it does not undergo the rigorous security audits found on the Google Play Store. Using such an app involves sharing private data through an unofficial "bridge." This exposes the user to potential data harvesting, account bans by WhatsApp official, and malware infections. On a system as old as Android 4.4.2, which lacks the robust permission managers and security patches of modern Android versions, a compromised APK can gain total control over the device with minimal resistance.
