server troubles on startup

It seems that whenever i go to start up my server right when it finishes going through the queue it crashes or something. at first it will say it's offline then it will not display a timer for when it will automatically shut off and will refuse to let me join. when i go to login to my server it will say it's still in start up and i should wait for a bit, i waited once and it shut itself off and i have tried multiple time to start it up with the same exact problem. i have no idea what i can do at this point. yesterday i got rid of everything my server since it would no load in the nether( i got rid of all my plugins and did a reinstall to fix it and it worked.) and it would run perfectly fine. today if is just being stubborn, even restarting it doesn't fix it

i wasn't able to find a way to copy it before it wiped it self
