“There is no editor available for” Can't open .cs

Question

My computer shut down while working on a project and when I opened C# again and recovered it, I got an error saying

There is no editor available \'for

Answer 1

There is no way to get the .cs file again (In my case after PC crash, two notepad files opened with no text in it, if I try to open the .cs file with notepad++ only null separator values). Have to redo the code again.
