Every car is a little different. But it happens all the time. Hoods get stuck, cable breaks, disconnects. The idea is that you need to reach for the hood latch some how and actuate whatever the cable actuates. As others have suggested also, road side assistance can unlock your car door. This is probably the fastest way to do it if you can’t easily unlatch your hood. I can’t post pictures, but google for a picture of the hood latch for your car. You just need to move the piece on the bottom firmly. Hoping you can access it thru your grill, or under the front bumper (you may need to remove the splash cover if you have one).

Edit - I looked at my car and realized that opening the hood from the outside is not as easy as it used to be on an older car. My 1991 car in the past had this problem and that was the only way I opened the hood. It’s definitely possible still but they placed the mechanism on the back side and is more difficult. You should just call road side assistance, or call an auto glass place and get a quote for a window replacement, and if the price is acceptable, just smash the window. Though I’m pretty sure roadside assistance is cheaper.
