UE5 fails to start on Linux

Hello there @bok!

Checking your provided log, the engine is starting successfully,reaching the project browser, but then abruptly closes during project menu. A few lines to take in consideration:

ImportText (Variants): Missing closing parenthesis: (Name=“TwinStick”,LocalizedDisplayNames=((Language=“en”,Text=“Twin Stick”)),LocalizedDescriptions=((Language=“en”,Text=“A twin stick shooter game with infinitely spawning enemies.”)),SharedContentPacks=((DetailLevels=(Standard),MountName=“Variant_TwinStick”),(MountName=“Input”,DetailLevels=(“High”)))

The entry shows a parsing error in a text file, most likely a sample project definition, since it’s mentioning a “TwinStick” reference. Usually, this type of conflicts are tied to corrupted installs. Potential fixes to test:

  • Re-download and refresh your prebuilt binaries, which should resolve the parsing error

  • If the issue persists, we can clear more potential corrupt data, via deleting “Intermediate” and “Saved” folders within your engine directory

  • Also, please make sure both your nVidia drivers and Vulkan are up to date, if possible, via a clean installation, and using any developer software version available
