I have NET Framework 4.7.2 Web Application which was running fine till last week.
Recently I have updated Windows OS. Details:
Edition: Windows 10 Enterprise Version: 21H2 OS build: 19044.1348 Experience: Windows Feature Experience Pack 120.2212.3920.0
After upgrading the OS, I started to have following issue while launching the WebApplication on IIS Express.
Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in C:\Program Files\IIS Express\iisexpress.exe.
Additional Information: The runtime has encountered a fatal error. The address of the error was at 0xc488d19a, on thread 0x57d4. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.
I don't know how to fix this issue.
If I host the application on IIS it works fine.
