What were you trying to do that didn't work?

When starting the RHEL-9.4 installer in graphical (or VNC) mode, there are the following error messages printed on TTY1:

05:28:18 Attempting to start vncconfig 
MESA: error: ZINK: failed to load libvulkan.so.1 
glx: failed to create drisw screen 
failed to load driver: zink 

There doesn't seem to be any problem running the installation itself, graphical mode starts successfully. At least when testing in a VM.

Update:
There are also other similar errors on different systems architectures:

MESA: error: ZINK: failed to choose pdev
glx: failed to create drisw screen
failed to load driver: zink

(See RHEL-20565)

Another problem on s390x:

MESA-LOADER: failed to open zink: /usr/lib64/dri/zink_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/dri, suffix _dri) 
failed to load driver: zink 

Please provide the package NVR for which bug is seen:

RHEL-9.4.0-20240122.10
mesa-23.3.0-1.el9
vulkan-loader-1.3.268.0-1.el9
