ApplicationPool randomically crash handling HTTPS request

I have an issue with an ASP.NET site running in a IIS (10.0.14393.0) on Windows Server 2016.

Randomically, the page I opened in the browser (only when I open with HTTPS) return me error:

I have then searched on the Windows Server, looking for meaningfull log about the error.

What I have found is that every time I get that error, the application pool associated with that page crash.

In the windows event log I have those logs two error (they appear every time with that order):

Name of the application that generated the error: w3wp.exe, version: 10.0.14393.0, timestamp: ------
Name of the module that generated the error: msvcrt.dll, version: 7.0.14393.2457, timestamp: ------

I have no idea of what to do to resolve that issue, so any hint is welcome.

First please check the account under which worker process w3wp.exe is running have read/write permissions of your hosting folder(such as Inetpub folder), then delete project bin and obj folders and try again.

The Exception code 0xe0434352 is a generic CLR exception code. It is thrown when there is an internal issue in the application. In most cases, it is either System.NullReferenceException or System.ArgumentException. There is no straightforward way to solve these kind of issues. I would recommend debugging the application in Visual Studio to get more details. In case you don’t have access to the source code, you can use DebugDiag or WinDbg for further troubleshooting.
