Hello I'm new, and there is an issue. (1.3.5)

I just got signed up and started today, but I have been playing Terraria PC for a while now. I love playing video games, but there is a HUGE issue that I am having and I want some help as soon as possible. In my Terraria game it loads up fine plays fine, but then about 63% or 96% through saving the world data and it crashes. I tried playing for a little amout of time. *Crash* Auto save enabled. *Crashes randomly* No auto save. *CRASHHHH* I would really appreciate it if I got some help. Also...
