That’s interesting. Can you tell what error message you receive when it crashes? Does it crash when you’re trying to type anything, or when you press the Login button? Do you have Remember Me ticked?
Also, if you look up the installation folder, there should be a logs/ directory, which contains some files starting with the name “session_”. Can you look into them to see if there is anything else then “Loggin started…”?
Which OS are you running on by the way?
