Every time i hit play Unity crashes

There could be lots of things at play here. More information could help pinpoint a cause.

When did the crashing start happening? If you're doing 'big bang' programming this could be hard to know (i.e. not testing often and adding a lot of new code/functionality at a time).

How are you certain this is a Unity bug? If you've ruled out self-error, then you'd have to switch to a different version of Unity and try again (though I'm not aware of this kind of development-breaking bug atm).

Without more information, the most likely culprit is likely an infinite loop. Do you have anything in an Update() call or like a while loop that could be looping forever? The best place to start looking is in your Start(), Awake(), and Update() methods as this is where everything is kicking off especially if the crash happens right away. Start editing out method calls, adding in Debug.Log() lines anywhere you're suspicious and try to pinpoint a cause.

Dealing with crashing is super frustrating and can be very time consuming. I'd start with a bottom-up approach (lots of commenting out, and slowly adding things back until you find the crash) as opposed to working down (unless you already have some suspicions of the cause).

Good luck, and if you still have issues please add some more details with what you find and I'm sure you can reach a resolution!
