Welcome to the forum, @sarowmir
I say the same, could you upload the contents of your stonehearth.log? It could be useful to determine why is it crashing.
It should be in a path similar to this one: C:\Program Files (x86)\Steam\steamapps\common\Stonehearth\
So you can run the game but it crashes after 10 minutes or so?
Can you tell me which things you tried? So I don’t suggest things that you already tried and didn’t work 
Some more questions just in case:
-Did you reinstall the game?
-Did you update your graphic drivers?
-Did you enable Stonehearth through your antivirus/firewall?
-Did you try running the game with the 32bit version?
-Have you checked this
thread to see if you have any of those programs that can interfere with the game?
