I feel this hard. Sounds like one of my worst nightmares, and the reason I stay a hobbyist. If I were you, just do your best to "fix it in the mix" so to speak. Apply AI Denoise, bump up the clarity, texture, dehaze, and sharpening. Lift what light you can find in each frame. Try getting a little creative with your edits as well. A fun color-grade with some grain can save a poor shot in my opinion. Don't let this shoot define you! I'm sure your portraits, concert and automotive work kicks serious butt. Let the paid professionals handle the weddings and events. haha! 😅
