A JNI error may occur if an external application disrupts the Minecraft game. To remedy this, you can perform a clean boot and disable processes individually until you identify the source of the problem. Once you have determined the troubled process, you can remove it, and hopefully, the issue will be resolved.
4. Uninstall the previous version of Java
To avoid getting the error message ‘A JNI error has occurred’ while running Minecraft or any other JNI errors, ensure you have the latest version of Java installed and that it is not affected by any prior installations on your system.
