After test,the last nightly i can boot (gives me setup) is v20.0.0-dev12+nightly5.9

higher version will pull up my Visual Studio and says an unhandled win32 exception occurred in ALVR Dashboard.exe

usually it will auto close,but if i hang it up,i can see there is a windows error in task manager,its just a "Instruction 0x0000 7FFB CAE3 8EC0 at referenced memory 0x0000 0000 0000 00B0,The memory cannot be read" error

Do you mean when you open the dashboard or start SteamVR after opening the dashboard?

@Whale-Splas The latest nightlies have also debug builds, please try that. Launch the dashboard from the command line and you should be able to read a more descriptive error.

vulkan-1.dll cause an access violation (by read 0x0),and the alvr dashboard does showed up,but at the same time it throws thiis exception,so every thing just shut down,is this some null pointer problem?
