FileNotFoundException on first authentication attempt #43

Closed Peaj closed 2 years ago

Peaj commented 2 years ago

File.ReadAllText in LoadPKCEToken fails on first authentication attempt because the file has not been created yet. The code only checks if the file is empty but throws an exception if it does not exist. A simple File.Exists check should fix it.

Tested in Unity Editor version 2021.1.12f2
