An error occurred while writing to logger(s). (Cannot open log for source '.NET Runtime'. You may not have write access.)

I have created a web application in .Net core 3.1 and trying to access DB using EF Core. While accessing it, I am getting below error. Strangely, it was working before and nothing have changed on application side.
