iOS 18 photos app error attempting to save portrait photo with definition or noise reduction edits
Hardware: iPhone 16 Pro Max 1TB
Software: iOS 18, Photos app, Portrait Mode photo taken with rear camera
Editing the photo using ƒ, lighting mode (Studio/Normal etc.), automatic adjustments, cropping, are all working fine. Any edit made to Adjust->Definition (even only "1") results in a long spinning wheel then a dialog "There was an error saving this photo. Please try again later." Exact same result if Adjust->Noise Reduction is edited at all (again, any value from 1..100). Adjust->Sharpness does not trigger this error.
Pretty sure this is actually a bug in Photos, but thought I'd run it through community thoughts before trying to open what I know will be an ignored radar. Any ideas about what might be going on? I have iCloud Photos turned off (default setting for me, I don't use iCloud Photos).
