At random times, I get an alert window:

Windows - Application Error
The application was unable to start correctly (0xc0000022).
Click OK to close the application.

(When I say "random times," I mean it's frequently when I'm in a Zoom meeting with a web browser open, and not much else. I am not starting or stopping other programs at the time. I have not confirmed if it only ever happens during Zoom meetings; that just happens to be when I'm sitting in front of my computer for extended periods of time.)

My investigation so far has revealed:

  • Process Explorer says the window's parent process is "C:\Windows\System32\csrss.exe" which is a core OS process
  • According to this Superuser answer, "0xc0000022" usually refers to an Access Denied error, but I'm not sure what access would be denied to csrss.exe.
  • As a core OS process, terminating csrss.exe typically leads to system instability, but when I click "OK" on this alert window, nothing visibly changes.
  • Various articles online claim csrss.exe is a common filename for viruses to use, but I confirmed that my csrss.exe's path, signature, and hash are all legitimate.
  • Running sfc /scannow returns no errors

UPDATE:

  • Just because csrss.exe is the error window's parent doesn't necessarily mean it's what's causing the error; this StackOverflow question may suggest that csrss.exe is always the process that spawns the error window, regardless of what program experiences the error.
  • The strangest thing so far is that the error window title just says, "Application Error." Most troubleshooting info I've found for this error code online describes having a specific program's name in the window title.

I'm hesitant to do something major like an OS reinstall, because like I said, nothing appears to go wrong when I click OK. But the repeated presence of this sort of error makes me worried that there is some hidden system instability or problem occurring.

Anyone know what might cause this? Or how I can investigate this further?
