Might me a multitude of things. Is your system low on memory and Windows killed the process? Or did you recently add new media? A single weird file might? cause the issue. Anything specific you do just before it crashes?
no memory is fine at 20% and nothing i do . like to day it crashed 4 times , i restarted my computer and my internet. it just go blanks and plex says my server is disconnected
And then uninstall the server with this guide, to make sure no traces are left that could confuse a new PMS installation, and then re-install with the normal installer. Steps to restore are in the first link as well.
