Hooking Every Shot Suddenly

So I play pretty often, 1-3 times a week, currently a 13 hdcp. Over my last 2 rounds, I have developed a nasty (I mean really nasty) hook that I can’t get rid of. It came on suddenly on the 10th hole, after shooting a good for me score on the front 9. I normally hit the ball pretty straight, but right now I can’t even do it with my best club. It’s definitely the worst slump I’ve ever been in and it’s pretty dang annoying!

Not looking for swing tips I just want to know if this type of thing has happened to anyone else? How long did your slump last? Did you need a lesson to get back to your normal self? Thanks!
