Lilly.... thanks for posting those screenshots...... Obviously you can see that the Memory showing in screenshot 2 has gone up to 5573 MB which is pretty much why the game locks up.
I run the game on a low end pc with 4 gig of memory in fullscreen mode and I have not had memory issues like you are having.
Some questions:
1. Have you only recently started playing Rising World and had this issue from the start..... or have you been playing the game for some time and this problem has only started up in the last few months?
2. how long do you play before this problem occours?
3. Have you uninstalled Rising World and reinstalled it to see if that fixes the problem?
4. Some games are effected by the type of antivirus software you are running. Have you tried running the game with antivirus temporarily suspended. If your antivirus is constantly scanning your game while you play this may be causing the memory issue because the game creates a procedurally generated dynamic world and maybe this is causing your antivirus to constantly scan the game.
5. A possible workaround for this issue might be to use the dedicated server to play single player on a world locally. If you start a server, can you actually join it (go to "Multiplayer" -> "Connect to IP" -> enter localhost)? If that works, could be more or less a replacement for the singleplayer mode
6. There is a post in the forum from November last year where someone had their game lock up and the developer left some comments. You may want to check these out.

7. Create a report file and copy and paste it below
Creating a reportfile:
1. Open the game and stay in the main menu.
2. Open the game console by pressing the "^" , "´" or "~" -button on your keyboard.
3. Type in report and press enter.
4. Close or minimize the game and open your Rising World game folder.
5. There should be a textfile with "report_" and then a long number, e.g. "report_1234567898765". Open this textfile (it should state todays date) with an editor and paste its content here for us to look at.
