"Too many open files" error when bundling - watchman installed, ulimit=2048

[dancherb]

I have a lot of images to bundle with my app (a few thousand, as part of an emoji pack), and recently (after further images were added) I'm receiving the following output and error when attempting to create a bundle with the following command:

react-native bundle --platform=android --dev=false --entry-file=index.js --bundle-output=android/app/src/main/assets/index.android.bundle --assets-dest=android/app/src/main/res

result

Loading dependency graph, done.
Loading dependency graph...info Writing bundle output to:, android/app/src/main/assets/index.android.bundle
info Done writing bundle output
error EMFILE: too many open files, open 'C:\App\node_modules\bugsnag-react-native\package.json'.
Run CLI with --verbose flag for more details.
Error: EMFILE: too many open files, open 'C:\App\node_modules\bugsnag-react-native\package.json'

I can see that the latest images have not been added to res and do not show in release builds of the app.

I'm using Git Bash on VSCode on Windows 10.

I have tried increasing the ulimit open files count with ulimit -n 2048. Before increasing the limit, the error showed a different file for the "too many open files" example (unrelated to Bugsnag, the file currently shown).

Watchman is installed, and I have tried re-installing it. Running watchman.exe -v returns 4.9.4. Maybe it's relevant that watchman is not accessible via watchman -v without the .exe? This seems to be how Bash works on Windows.
