Server keeps crashing on start.

Hello! I set up my server and everything was going well, all my plugins "installed" correctly as well, but when I went to start my server again (because it was offline) it went all the way to "preparing spawn area for ever world" and would stay at 0%, then crash. If I could get this fixed let me know!

I have found a way to fix this, but it just recently stopped working (the "patch" I made.) What i did was completely wipe the world, delete the end and nether saves then generate a new world and add a new map. Although that did work for a little bit. My friends who were on the server got kicked (so did I) then the server wouldn't let us join back although it was online, resulting in the countdown to run out and the server going offline.

Edit: I don't care about losing data right now, but if I wanted to make progress on the server I wouldn't want to wipe.

Now it is saying this when I try and go online. (crashes) I did what it said, but it still says that after crashing again when attempting to launch. https://mclo.gs/XWGg7ij

Hey, I found out it was just a memory error. I used less plugins and it worked completely fine. Thank you for the help.
