When you attach something, please only attach, and do not try to insert it to the post. That way it will work. Right now it doesnt work. If you can give me a screenshot of the crash, we could discover something.
So I did a quick test on my Windows workstation via a VPN and it works right off the bat. I logged in to a troubleshooting account on -Sharing without ticking remember me. It logged me in normally and stay logged for 5 minutes. I didnt test it for more than 5 minutes. I can say it works normally.
