Unreal Engine 4 crahses

Question

My Unreal Engine 4 keeps crashing This is what its showing EXCEPTION_ACCESS_VIOLATION reading address 0x00000048 This is the error I'm getting If anyone could help me rectify it that would be great. Cheers!

Answer 1

This is the most common C++ error in Unreal Engine, and if you're writing code it's completely normal to see the engine crash if appeared one of the following errors:

• calling method or variable on a nullptr
• calling method or variable on a non-initialized pointer
• calling wrong methods in class constructor (you can't modify game states on the constructor)

If you're not writing c++ code try to verify the Engine's installation going in the launcher -> library -> engine -> versions, and click on you're installation and "verify".

Answer 2

Try verifying the engine from the Epic games launcher

1. Open Epic games launcher
2. Go to the Unreal engine menu
3. Open library
4. Go to the engine versions
5. Click on the icon right to the launch button
6. Click on verify
7. Then wait for the engine to be verified

Hope it works

Answer 3

There is a very little information, when does this crash occurs? Are you using C++?

What I would suggest but it's a totally arbitrary guess (due to lack of information):

1. Check you are not using Nullptr
2. You create all the components in C++ on constructor
3. You are not using variables (except the components ones) on the constructor.
4. Related to point 1, Check if you were using a reference, it wasn't destroyed.

This is just a quite generic tips, if you can give more information maybe we'll find a more accurate solution.

Hope it helps
