Good Day Everyone

We published our Blazor Server side application to our local server which is Windows Server 2019, now the site becomes unresponsive when it encounters an error on the system, a JIT Debugger shows up on the server, which is the main cause of the sites unresponsiveness, now in able for the site work again, some from our technical team must close the JIT Debugger on the windows server, and also if we are updating the websites IIS, we cannot overwrite or delete the files inside the websites folder because the JIT Debugger shows ups on the server side. We disabled it on the Visual Studio 2019 that is installed on the server, but still, it still shows on the server, is there a way for the JIT Debugger not to show up on the server and makes the application working?

I hope someone can help me on this.

Thanks and regards.

    Hello

    Thank you for your question and reaching out. I can understand you are having issues related to Disabling JIT debugger on Windows

    1. Delete (or rename) below files.

    C:\WINDOWS\system32\vsjitdebugger.exe
    C:\Windows\SysWOW64\vsjitdebugger.exe

    1. If your computer is running a 64-bit operating system, delete the following registry keys also after taking backup.

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\WindowsNT\CurrentVersion\AeDebug\Debugger
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\DbgManagedDebugger
