game keeps crashing

i recently have been trying to make a map but whenever i try a test run at my map it sits at the loading screen for a couple minutes then crashes every time.
is there anyway to fix this?

To add on to what Nadeox1 said, after you try that just go on and clear your cache, it can do some funky things after you don't clear it for a while.
