Program received signal SIGSEGV, Segmentation fault.

The backtrace points to libvulkan loading the Radeon driver:

My system has an Intel GPU:

$ lspci -s 0:2
00:02.0 VGA compatible controller: Intel Corporation Iris Graphics 540 (rev 0a)

The Intel driver is installed:

$ ls -l /usr/lib64/libvulkan*
-rwxr-xr-x 1 root root 2625088 jul 24 04:26 /usr/lib64/libvulkan_intel.so
-rwxr-xr-x 1 root root 1655912 jul 24 04:26 /usr/lib64/libvulkan_radeon.so
lrwxrwxrwx 1 root root      19 mai 27 22:52 /usr/lib64/libvulkan.so.1 ->
libvulkan.so.1.0.41
-rwxr-xr-x 1 root root  239600 mai 27 22:52 /usr/lib64/libvulkan.so.1.0.41

Both files drivers are installed due to a dependency in package management, but
clearly the Radeon one should not be used. The driver should validate that it
is in the correct HW and bail out if not.
