Just in case anyone else has the same problem. I did not play Everspace for a couple of months but when I wanted to play it recently, It did not launch and displayed the following error:
./EverspaceWithShippedLibraries.sh: Zeile 3: 24438 Speicherzugriffsfehler (Speicherabzug geschrieben) LD_LIBRARY_PATH="$UE4_PROJECT_ROOT/RSG/Plugins/VlcMedia/ThirdParty/vlc/Linux/x86_64-unknown-linux-gnu/lib/:$LD _LIBRARY_PATH" "$UE4_PROJECT_ROOT/RSG/Binaries/Linux/RSG-Linux-Shipping" "$@"

I can be start with ./start --syslib
but that should be fixed.

Running on Manjaro Linux.

I have exactly the same problem on Linux Mint.
All worked well, with the classic launcher.
But today I have to use the second launcher, which adds libraries.

No EVERSPACE update, so I guess the problem came up as a result of a system update.
Nothing to do with the removal of 32-Bit support from Linux, EVERSPACE is 64-Bit, like Manjaro and Mint.
so what happened?
The kernel ? (I don't think so.)
MESA ? (I don't think so.)
LLVM ? ? ?

I agree that we need to understand what happened, and do something about it.

Thank you Themken, happy to see you ;-)

I found this command to check the required dependencies, and if they are in the system: ldd <binary file>
I haven't tried it, and not sure if it would help to understand.

I looked at the update history of the intel microcode, I won't be affirmative on the defect match, but it's quite possible:

I cannot think of anything else. Not an expert on Linux.

I have this problem on two PCs with different Ryzen processors so that doesn't seem to be the cause.

I just bumped in to this. The game would crash immediately using either launcher; the console reported "Illegal instruction."

I did a little poking around, and discovered that even the "system libraries" launcher was overriding a huge number of libraries, including libc -- NEVER a good idea.

I patched the launcher script to remove the overrides, and now EVERSPACE appears to launch and run without issue.

EVERSPACE 1.3.5.3655
System: Debian Sid

Here's the patch; basically it removes PROJECT_LIBS_DIR from the LD_LIBRARY_PATH environment variable. Hopefully the forum software won't mangle this too badly:

That makes it work.
