Unreal doesn't open any projects - 5.4.4 Linux

Development Getting Started & Setup

1

Hello! I am trying to open my project on Linux, but it is not working. It starts to load, but then it gets stuck in compiling shaders. Tried everything that I could find, but nothing is working. Decided to test if it was a problem with the project, and tried to create a empty project from the start options, and it gives the same error. This is the error that appears on the crash log:

Does anyone knows what it is happening and how to solve? Thanks in advance :slight_smile:

Well, I solved most of it by checking the Direct X compiler. It was, uninstalled. But now, I have a different issue. The crash still happens in the Compiling Shaders part of the part of the loading the project, but it gives a new error:

Caught signal 11 Segmentation fault

libc.so.6!UnknownFunction(0x3d1cf)

There’s one other thing. If I remove the DefaulEngine.ini from the project file, it opens the project. It just messes everything up, including where it is recognizing the mouse to be pointing.
