Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x00007fff1d087718

infoloren · October 22, 2022, 10:31am

Problem:
I am unable to start the editor again, and when I had it opened I was unable to build ( same error )

What I did:

I was trying to build the project, then I got an unknown structure error on a variable so,
I refreshed the structure variable.

Then I tried to build the project again and I got that error. I closed the editor and I am not able to open it again.

I tried a few solutions around the internet and the Epic forum, like this one:

EXCEPTION_ACCESS_VIOLATION reading address ” crash log

But it didn’t work.

Here is the full stack trace:

Well since it builds fine this means it is runtime error. You should be able to backtrace to see what has change vs. your previous successful runs.

However what might be of better help is if you’d download debug symbols as this stack trace is useless because you cannot see anything. Just click on Options in Epic Games Launcher for your engine version and check Debug Symbols (around 20 GB). Then you’ll be able to see better what is going on. However the best solution for this is to revert the changes you made or at least focus on what has been changed recently.

Really not much here to help with.

Hello, @Ligazetom thank you for your quick answer.

Good point about the debug symbols, I didn’t know it. I will use it for sure.

I follow your idea of looking at what changed, in this case, what changes are the feature, so I cannot revert it.

But what solved ( Or I think solved ) my problem was muting my PC, I mean you mute the sound output in windows and the cooking process goes fine and the build is finally.

This cooking process takes less than a minute for some reason, but it packs the game properly and I am able to run the build, many things in the build are wrong. I am still checking that but at least a .exe is generated.

A thing is that if I do not mute my PC, I get an unknown structure error rather than this EXCEPTION_ACCESS_VIOLATION that for example here:

EXCEPTION_ACCESS_VIOLATION reading address 0xffffffff - UNREAL CRASH

They mention that to solve this, an option is to change the setting of your PC Audio:

Thank you for sending over your system information. That specific error message is often due to your system sound configurations. Can you try to change your sound output rate to 192 kH or lower?

Summary

Greetings Infinitycycle,

Thank you for sending over your system information. That specific error message is often due to your system sound configurations. Can you try to change your sound output rate to 192 kH or lower?

You can do this by following these steps:

Right-click on the speaker icon in the bottom-right of your screen and click Open Sound Settings
Click on Device Properties > Additional Device Properties
Under the Advanced tab, select a 192000 or lower rate
Press OK and retest

OR

Press the Windows button, type Sound Settings and press Enter
In here, under Advanced Sound Options, click in “Customise app volumes and the speakers or devices they use”
Click on “Reset”
Close the window and retest the game

Regards,

Anyways I am still checking if this finally allows me to get a valid build.
