Blender Version
Broken: (example: 4.2
6c78f79740
, main, 2024-02-28, as found on the splash screen)Worked: Blender 4.2 Alpha, older version (only startup, not rendering, on render crash)
Short description of error
Two main crash with Vulkan, the first time gives a txt file report, the second time crash, but load a part of UI of Blender 4.2 Alpha
Exact steps for others to reproduce the error
Refer to https://devtalk.blender.org/t/blender-vulkan-status-report/25706/21
Path to follow:
Open CMD as Administrator
CD + folder path of Blender 4.2 Alpha
Digit exe file (blender.exe) + --gpu-backend vulkan
Blender doesn't open, crash instantly with txt file as main error
Then blender.exe blender --factory-startup --gpu-backend vulkan
Seems blender will open, but crash, but I can see UI at beginning
As main error:
C:\Users\giorg\Downloads\blender-4.2.0-alpha+main.6c78f7974098-windows.amd64-release>blender.exe blender --factory-startup --gpu-backend vulkan

Blender quit
Here it does not crash.
I see some messages in the console:
Even not being able to repro, this feature was implemented to get some insight on supported platforms. So, tagging @Jeroen-Bakker
WARNING: dzn is not a conformant Vulkan implementation, testing use only.
is saying that your platform doesn't have a vulkan conformant driver installed. Please make sure that a vulkan conformant driver is installed and try again.Conformant means that the driver works as expected to the vulkan specification. If this isn't the case some features that is required might not exist or isn't available. Other software also have the same issue https://duckduckgo.com/?q=dzn+is+not+a+conformant+Vulkan+implementation&t=newext&atb=v407-1&ia=web It seems to be that due to a recent software update from windows store broke the vulkan driver. No vulkan application could be run, even the simplest demo.
might point to a solution (source https://stackoverflow.com/questions/77913326/vkcreateinstance-crashes-even-after-updating-drivers)
I will close this issue as the platform didn't meet the minimum requirements to run vulkan.
Thanks, I fixed by unistall the software from Window 11 App, on control panel I didn't find it. Now it works and it open as well
@Gioxyer If you say things are working, does this issue need to be Open or can it be Closed now?
It can be closed, thanks for helping
