Hi! While building my project for Linux x64 I encountered this error: The instruction at ... referenced memory at ... . Memory cannot be Read
But the log showed:

Moreover, this error also occurs when trying to pack projects from the Starter Kit. What could be the problem? How can this be solved?

Hello there @Andrew_Sor!

Checking through your log, the conflict seems to be related to UBA functionality, considering the lines below:

UbaSessionServer - ASSERT: ERROR: Access violation reading at address: 0x000002C2FE003FDC
UbaDetours.dll
ucrtbase.dll
combase.dll

Please test packaging your project with UBA disabled, via going to Project Settings > Platforms > Linux > Uncheck “Use Unreal Build Accelerator”.

After that, clear your project’s cache, by deleting folders “Intermediate” and “Binaries” from your main directory.

As an extra measue, I would make sure that platform support is enabled for this build. Please go to UE’ s Library, and ensure that Linux is checked under target platform.

Unfortunately, I couldn’t find this checkbox…
Linux checked in target platforms in Epic Game Launcher in UE settings. But I checked it recently, first I installed Unreal Engine without it…

I have the same issue in 5.5.4. I also cannot find the checkbox he is referring to. Just making a fake .sym file and putting it where the manifest expects a sym file to be seemed to allow me to package at least but it would not allow for proper debugging.

How did you make the fake .sym file? I tried creating an empty file with that name, but it didn’t help…

Since I didn’t get any information on where to disable UBA, I found and followed this tutorial:

Now my project builds fine. But I would like to know what UBA is responsible for?

I’m following this thread. After making changes in BuildConfiguration.xml . I’m building a linux based Dedicated Game Server, I’m using Engine Source Build . I cleaned the intermediates and binaries and rebuilding the project again .
Will let here know how it worked.
