ios – Expo 54 Monorepo App crashes with ‘NSInvalidArgumentException’, reason: ‘-[RCTView setColor:]: unrecognized selector sent to instance 0x11fb633f0’

I’m working on an Expo app inside a monorepo.

Setup

• Expo Router app
• Monorepo (pnpm workspace)
• Shared UI package: ui-native
• gluestack-ui is installed and initialized inside ui-native

App imports gluestack components from ui-native.

The app crashes immediately on launch only when I use < Stack /> in my root layout.

If I remove < Stack> and its children and render any simple component (even a View or a Gluestack Button), the app works perfectly.

As soon as is added back, the app crashes on startup.

What I’ve tried

• Deleted node_modules
• Deleted ios folder
• Reinstalled dependencies
• Rebuilt app
• Verified gluestack works when used without
