My world keeps crashing

Hi,

my world was working perfectly and suddenly it randomly crashed. I was able to play for a few days but now there is no way I can get on it. When I want to start up, the server saves and I can't get on it. Do you know what could be wrong ?

now I have this crashreport

hi,

I don't understand the problem because I have installed create. I have also tried reinstalling this several times and the crash keeps happening. At this point, I don't know what to do.

I have also done a backup to the moment when everything was working perfectly and then when I start the server, the crash occurs again.
