Font loading error only when doing a Testflight build

Describe the bug

I'm using some custom fonts, and have followed the instructions for custom fonts as follows:

Put the fonts in ./assets/fonts/
Referenced the folder in react-native.config.js, like:

module.exports = {
  assets: [
    // TODO: link documentation about fonts to this section
    // If you need to add non-google fonts (those not available through the `@expo-google-fonts/**`
    // packages, you can add them to the referenced path below and uncomment this line.
    "./assets/fonts/",
  ],
}

Run npx react-native-asset

In ./app/App.tsx:

const [areFontsLoaded, fontError] = useFonts(customFontsToLoad)

in ./app/theme/typography.ts

export const customFontsToLoad = {
  ApercuBold: require("../../assets/fonts/ApercuBold.ttf"),
  ApercuBoldItalic: require("../../assets/fonts/ApercuBoldItalic.ttf"),
  ApercuLight: require("../../assets/fonts/ApercuLight.ttf"),
  ApercuLightItalic: require("../../assets/fonts/ApercuLightItalic.ttf"),
  ApercuMedium: require("../../assets/fonts/ApercuMedium.ttf"),
  ApercuRegular: require("../../assets/fonts/ApercuRegular.ttf"),
  ApercuItalic: require("../../assets/fonts/ApercuItalic.ttf"),
  RecoletaRegular: require("../../assets/fonts/RecoletaRegular.otf"),
  RecoletaBold: require("../../assets/fonts/RecoletaBold.otf"),
  RecoletaMedium: require("../../assets/fonts/RecoletaMedium.otf"),
}

When I do local builds of the app, the fonts load fine. When I do a release build on XCode, the fonts also work fine .When I do a release build and upload to Testflight, the fonts fail loading and I only see a white screen in the app.

I see this error: E_font_file_not_found coming from Expo-Font.

Not sure if this is an issue with expo-font, or an issue with the way Ignite's Xcode project is set up.

And ideas or things I could try?

Ignite version

8.4.5
