i had a period like this when i couldn't hit a SW more than 40m no matter how hard i hit the ball. i went through a 3 month period where i only left it for bunkers and used my PW instead as i hit this club confidently.

maybe try using your PW for a short period of time until u get your confidence back. then swap to the SW.

other than that. try putting the ball back in your stance and focus hitting down on it a lil more with stiff hands for a short 10 - 15m chip which should land soft and quick.
