For many players, modifying Minecraft is the most interesting part of the game, but sometimes, too many mods can cause your game to be unstable.
In such situations, playing is practically impossible due to all the frequent crashes, one of which we’ll be covering in the guide below.
If you’ve recently experienced a Minecraft crash with the “It looks like you are using an unsupported modified version of the game” message, you’ve come to the right place.
Let’s get right into it.

The Problem Explained
Minecraft is known to crash every once in a while, especially after recently installing texture packs, mods, and other game-altering files.
Unfortunately, the “it looks like you are using an unsupported modified version of the game” error is caused by the same thing.
However, the game crash report also contains an error log that is often very helpful for solving the problem without too much effort.
Since every player sees a different error report in the game crash window, it’s not easy to say which files you should specifically remove to get rid of the error, but following the path listed in the message will surely make things much easier.
In short, if you can see the name of a specific mod or files in the crash report, and you’re sure that you’ve installed those lately, removing them (even temporarily) will help you narrow down the list and find out what’s causing your Minecraft to crash.
Finding a different version of the mod, one that is compatible with your device, is usually the best-case scenario, but if you’re unable to do that, entirely removing the mod is the next step.
Suppose this doesn’t work, or your crashes tend to occur sometime after launching the game and not directly at the start. In that case, there are a few other things you can do to overcome this problem besides uninstalling the possibly-unsupported files from your game’s directory.
Fix 1: Allow Minecraft To Use More Resources
Although playing “vanilla” Minecraft (Minecraft without any mods installed) can be possible on “lighter” specs, heavily modding the game files with fancy resource packs, textures and systems can easily overwhelm your computer.
As a result, the game can end up crashing due to insufficient resources, and this happens very often, according to the members of the Minecraft modding community.
If you already have a powerful system, but you’ve limited the number of resources Minecraft is allowed to use, we recommend “bumping” the amount by a little bit until you no longer experience the crashes.

Fix 2: Ensure You’re Using The Latest Mod Versions
Sometimes Minecraft mods are not compatible with specific game versions, and when there’s a compatibility mismatch, the game will end up crashing before loading the files.
This is why we always recommend uninstalling mods one by one until you find the source of the problem, and once you do find the faulty mod, you can research and see which versions of it are compatible with specific Minecraft versions.
Mod creators usually release a lot of updates containing fixes for compatibility issues and bugs, performance optimizations, and a lot more. If there’s a new update for your Minecraft mod, make sure to download it and read the developer notes as well.
Fix 3: Update Your Version Of Java
Java is required on your system for Minecraft to be able to run, and the same applies to the Minecraft mods.
Upon installing Minecraft, you unpack and install Java files as well, which is enough for when you wish to play without any mods. The Java version that comes with the game is enough for the game’s base needs, but it looks like mods require a bit “more.”
Some users reported that they weren’t able to run specific mods they manually installed before updating their Java to the latest version. This isn’t the case most of the time, but it’s worth trying if you have already tried everything else and it hasn’t helped.
Although playing Minecraft with dozens of mods can be fun, sometimes you have to “ease off” as frequent crashes take away the joy from the game.
When you start experiencing frequent Minecraft crashes, especially with the “It looks like you are using an unsupported modified version of the game” error, it might be a good idea to start uninstalling mods until you find the one causing the problem, as this is usually the case of an “over-modded” game.
