Answer 1

Can you please try with StreamWriter class?

If the file exists, it can be either overwritten or appended to. If the file does not exist, this constructor creates a new file.

Instead using TextWriter writer = File.CreateText(filePath) try to use

TextWriter writer = new StreamWriter(filePath, true);

If you pass true in constructor it should append text to file.
