Memory leak with newly created project via npx create-expo-app

[zollipaul]

Minimal reproducible example

https://github.com/zollipaul/testExpo

What platform(s) does this occur on?

iOS

Did you reproduce this issue in a development build?

No (tested in Expo Go)

Summary

I created a fresh Expo app using 'npx create-expo-app'. After launching it in the iOS Simulator and reloading the app a few times with CMD+R, I noticed a memory leak. This issue becomes apparent after about 10-15 refreshes as the memory usage consistently increases. Why does this happen? It doesn't occur with fast refresh. Additionally, the memory usage slightly increases over time even without reloading. If I reload with CMD + R or through the developer menu 'Reload', the increase in memory is much more significant. The current workaround involves frequently hard closing the Expo Go app and reopening it. (See video below for a demonstration.)

✔ Check Expo config for common issues
✔ Check package.json for common issues
✔ Check native tooling versions
✔ Check dependencies for packages that should not be installed directly
✔ Check for common project setup issues
✔ Check for issues with metro config
✔ Check npm/ yarn versions
✔ Check Expo config (app.json/ app.config.js) schema
✔ Check that native modules do not use incompatible support packages
✔ Check for legacy global CLI installed locally
✔ Check that native modules use compatible support package versions for installed Expo SDK
✔ Check that packages match versions required by installed Expo SDK
