ok so i beleive that your issue is treegenerator because i mean its basiclly tho only thing in red so i beleive that whatever is generating your world especially if its a mod is making a big issue that cant start your server because other then that your server crashed from outtve the blue.

It simply took too long to start.
All you can do is try again if you run a modpack.

If its custom modded, remove mods
