I have had this one a lot lately everywhere, sometimes just a few seconds after starting the game and sometimes I can play a while before this crash. Windows11, AMD 7800X3D, 4090 and 32GB RAM.
I found an old build 'Full-BB' (diegolix29 fork) that has a lot of hacks and skips but it skips the has the PM4 type 0 case UNREACHABLE_MSG and break.
So today I decided to compile the latest main with only this change in liverpool.cpp:
case 0: LOG_ERROR(Lib_GnmDriver, "Continue hack Unsupported PM4 type 0"); dcb = NextPacket(dcb, header->type0.NumWords() + 1); continue;

With this change it doesn't crash and the log looks like this when hit by a PM4 type 0:
[Render.Vulkan] tile_manager.cpp:TryDetile:394: Unsupported tiled image: R32Sfloat (Depth_MacroTiled)

I just tried Diego's fork of the build and it's severely worse there. I can't even get past 5 seconds.
Would be great if anyone could make a pull for hacking this OP code into the main branch. :/
