Game crashed and lost my entire server.

Logged into my minecraft file called PEW and the game crashed as it often does on my xbox one x and come to find out that my entire server after bringing back up minekraft IS GONE!! I am irritated beyond belief I created a nice little house and got pretty far in just building my whole settlement. This is messed up and I cannot seem to find the server anymore which sucks but I however have been having the game crash on me more than once after starting it up a few time sit seems there is a bug in this aspect as I should not be having the game crash. I dont have any issue with any other game at all. The crashing happens randomly and I have uninstalled the game and reinstalled the game countless times and it seems to work for a couple of days and then starts back up with crashing.
