The most common reason for the game crashing is running out of memory, typically due to too many assets. I would recommend you subscribe to and enable the Loading Screen Mod. It can help you save a bit of RAM and shows you your RAM usage as the game loads.

If your game crashes with a pop up saying something along the lines of "Oops, the game crashed" then it mentions a folder where you can find the log files from the crash. The error.log and the output_log.txt (player.log on Mac and Linux) will show what caused the crash. If you can upload them somewhere and link to them here, we can see what's up and if it is indeed running out of RAM.

This guide has some suggestions for where to upload the file as well as help you find the different log files.
