Lens Blur "Refinement Error" when adjusting Focus Range on the latest version of Lightroom Mobile (Samsung Galaxy A25 5G)

Device: Samsung Galaxy A25 5G

App: Adobe Lightroom Mobile (latest version downloaded from the Google Play Store)

Subscription: Adobe Lightroom Premium

Issue: Lens Blur opens and works normally. I can adjust the blur amount, bokeh shape, and all other settings. The preview is displayed correctly.

However, when I adjust the Focus Range (depth range) and tap Apply, Lightroom always displays the following error:

"A refinement error occurred. Please try again."

The effect is visible in the preview, but it cannot be applied because the refinement process fails.

I have already reinstalled the application, and the issue persists.
