[Android] IllegalStateException: Unable to load font from rc_paywall_fonts cache (FontWeight=600)

Description

We're seeing fatal IllegalStateException: Unable to load font crashes on Android originating from RevenueCat's paywall UI. The error fires during Compose layout/measure when loading a downloaded OTF font from RC's cache directory.

The exception is uncaught and the app terminates. We've observed this in production via Sentry on react-native-purchases@9.15.1 / react-native-purchases-ui@9.15.1.

Stack trace (ProGuard-mapped, frames not symbolicated)

IllegalStateException: Unable to load font Font(file=/data/user/0/<app>/cache/rc_paywall_fonts/8ca61878210e82fbc279cb412ab67adb.otf, weight=FontWeight(weight=600), style=Normal)

Caused by: IllegalStateException: Could not load font
  at c (SourceFile:81)

  ...
  at measure-3p2s80s (SourceFile:9)
  at u0 (SourceFile:41)
  at measure-3p2s80s (SourceFile:1)

The crash happens at measure time within Compose (measure-3p2s80s), so the paywall is mid-layout when the font fails to load.

Environment

What we expect

A downloaded paywall font that can't be loaded shouldn't take the app down. Either:

1. The font load should be wrapped in a try/catch and fall back to the system font, or
2. If the cached font file is corrupt, the SDK should redownload it before raising.

Questions

1. Is this a known issue with a specific paywall template / font weight (we see weight=600)?
2. Could the cached file at cache/rc_paywall_fonts/<hash>.otf be partially written / corrupt under low-storage or interrupted-download conditions?
3. Any guidance for users currently on 9.15.1 — clear cache, downgrade, etc.?

Happy to provide more Sentry breadcrumbs / exact paywall template ID if useful.

Start with the Android paywall UI font-loading path and the rc_paywall_fonts cache described in the report; use the Compose measure-time stack trace and reproduction environment to investigate. Done means an unreadable downloaded font no longer causes an uncaught fatal crash, with either safe fallback or redownload behavior verified.
