can't launch Windows Admin Center

Hello, I installed Windows Admin Center on Windows 10 22H2, but it won't start, the icon will appear on the tray for a few seconds and then disappear.

Check the event viewer and see a lot of errors similar to (The signing certificate (thumbprint: 67B1757863E3EFF760EA9EBB02849AF07D3A8080) for file 'C:\Program Files\Windows Admin Center\System.Web.Http.Cors.dll' is revoked.), it seems to be SSL certificate error.

I've tried safe boot and clean boot, but I can't start WAC.

Scanned system, found no corruption

and I found similar feedback elsewhere

this is log error files

And I tried to overwrite and install Windows while keeping the applications and files, but it was prompted that the win10 installation failed. Does this mean that my system files are damaged? But I used the dism command to scan, there is no problem with the system files

    Thank you for your question and reaching out. I can understand you are having query\issues related to WAC certificate error.

    To update the certificate used by Windows Admin Center, re-run the installer and choose change, then specify the thumbnail of another installed certificate.
