Why is UE crashing when I attempt to launch?

I am attempting to launch UE 4.8.3 for my class that I am taking this semester, but every time I click on launch I receive a crash report window and the engine never opens. I am running on macOS High Sierra 10.13.3. I need help quickly please! I have assignments due and need the engine to run

I am receiving the following crash report:

Hi,

This is a known bug with High Sierra and unfortunately you will have to use a more recent version of UE (4.15 or upwards) or downgrade to Sierra 10.12
