We have deployed a web application but experience random crash several times daily. Event ID 1000, 1023 and 1039 was found but there was not enough information to debug. It is running on Windows 2019 Standard Server with IIS 10, .NET Framework as 4.6.1. IIS Debug Diagnosis is running, and log captured. However, we don’t understand the logging details. Attached with the log file, could anyone give us some hints or direction?

    There are a number of "file not found" errors in your log.

    It looks like your server is missing some components and/or there is a mismatch between the installed Dot Net framework, and the application requirements.

    Is your IIS worker process set to use the correct .Net CLR version?

    You would need to ask your developer or the support team for the software that you running as to how you can verify that the server has the correct components installed.
