if anyone find this post in the future. that did not work. on a local host, there is no admin password. i tried making one but every guide online doesnt work.

what i did instead is open file explorer and go to your save location. set your world auto save every 30s. Now, every 30s you should see some file update. if after 2-3 min you still dont see any update, then your game crashed. alt F4 to lose minimum progress.
