vscode: Can't open vscode and it will flashback without anything

@shellvon That’s Great! I restart this service and vscode finally can be used. It seems that the service has shot down by an error. Thank you for your answer. sc query null sc create null binPath= C:\Windows\System32\drivers\null.sys type= kernel start= auto error= normal

@Ambit15 Accodring your error logs:

[3204:0616/131553.294:ERROR:electron_api_utility_process.cc(123)] Failed to create null handle: System cannot find the specified file.

It’s reported from electron source code here:

https://github.com/electron/electron/blob/e61359598214399cab97ca6a8ad541983059c331/shell/browser/api/electron_api_utility_process.cc#L123C25-L123C55

And you see, If electron run on windows and need utilityProcess, it’s need the NULL kernel service to run correctly. but it seems that your windows system was missing it.

You can check it by run sc command by using cmd.exe:

sc query null

it produce the output like this:

SERVICE_NAME: null
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

if you don’t have this service, you can create it by following command:

sc create null binPath= C:\Windows\System32\drivers\null.sys type= kernel start= auto error= normal

But you need make sure the file C:\Windows\System32\drivers\null.sys exists. you can download it by using google search or from another windows machine with same version.

Since my response indeed helped resolve the issue, I also answered the question on Stack Overflow in the hope of assisting more people who encounter similar problems.
