High frame rate locked on supported device (Redmi Note 13 4G)

My device is Redmi Note 13 4G.

When I first bought the phone, High Frame Rate was available in FC Mobile.

After changing system settings (RAM extension), the High Frame Rate option became locked and now says “device not supported”.

I reverted the settings, reinstalled the game, cleared data and cache, but the issue persists.

Android 13

MIUI Global 14.0.8

This seems to be a device compatibility / flag bug.
