There are a few remedies for this. BTDT.
Have someone "wiggle the hood slightly side to side while you attempt to free it. Doesn't usually work but hsd worked for some.
Ecklers, Davies Corvettes, etc all sett a tool (around $19.00) that will allow you with some patience, to go in through the door jamb and free the hood manually. My drivers side was a piece of cake. The passenger side was a PITA!!!
You can also make one, but as cheap as they are, I wouldn't waste the time...but thats me.
Finally, you can remove the tire, remove the side fender and go in though there. A lot of work but it works
