Hello @Adarsh

First thing to check is your model is in sync with the database. If nothing has changed add unhandled exception handling, write to a file and report back what was recorded. I noticed you indicated this has been tried and didn't work but it may be written incorrectly and if not this means the exception type is not caught-able which can happen.

I have a code sample that comprises of a class project for writing exception information and a simple test app on GitHub. To get both projects, create a batch file, insert the following and run.

Requires Git to be installed.

mkdir code  
cd code  
git init  
git remote add -f origin https://github.com/karenpayneoregon/csharp-features  
git sparse-checkout init --cone  
git sparse-checkout add ExceptionHandling  
git sparse-checkout add ThreadExceptionWindowsFormsApp  
git pull origin master  
:clean-up  
del .gitattributes  
del .gitignore  
del .yml  
del .editorconfig  
del *.md  
del *.sln

Otherwise, under debug menu select windows, exception settings and check "Common Language runtime exceptions then rerun the app.
