Can reproduce it, but it's fixed by lowering the graphics settings. Try
restarting the game without -vulkan, lower the settings and try again
with -vulkan.

Probably the same as:

https://github.com/ValveSoftware/Source-1-Games/issues/57

It really shouldn't crash due to this, so I suggest reporting this
upstream.
Nothing we can do in the packaging could help since this is the
proprietary driver.

Kind regards,
