How to fix Fatal Error! Size overflow in allocator

The error message is:

Fatal Error!
Size overflow in allocator.

UnityEngine.GUIUtility: ProcessEvent (int, intptr, boola)

This error message indicates that there is a problem with the Unity game engine's memory allocation. This could be due to a number of reasons, but some of the most common causes include:

• Running out of memory: This is the most likely cause of the error. Unity has a limited amount of memory that it can allocate to games, and if your game tries to use more memory than is available, this error will occur.
• A bug in your code: It's possible that there is a bug in your code that is causing it to allocate memory incorrectly. This could be a memory leak, for example, which is when your code allocates memory but doesn't free it up when it's no longer needed.
• A problem with your assets: In some cases, this error can be caused by problems with your game's assets, such as textures or models that are too large or corrupt.

Here are some things you can try to fix the error:

• Close other programs: If you are running other programs that are using a lot of memory, close them before trying to run your game again. This will free up memory for Unity to use.
• Restart your computer: Sometimes a simple restart can fix memory allocation errors.
• Reduce the quality of your assets: If you think that the error is being caused by your game's assets, try reducing their quality. This could involve reducing the resolution of textures, or using lower-poly models.
• Find and fix memory leaks: If you think that the error is being caused by a memory leak in your code, you will need to find and fix the leak. This can be a difficult task, but there are a number of tools available to help you.
• Update Unity: Make sure you are using the latest version of Unity. Unity updates often include bug fixes, so it's possible that the error has already been fixed in a newer version.

If you are still having trouble fixing the error after trying these steps, you can search for the error message online or consult the Unity documentation for more help. There are also a number of Unity forums where you can ask for help from other Unity developers.
