If the File was created by Companion before you try to test with the APK, it does not work, because the file was created by another app and no longer be overwritten / accessed by a new app (on Android 11+).
Two options:
delete the file via Companion before closing Companion or

This one doesn't work with Companion and the compiled APK on Android 11+ as it doesn't delete the text file when Companion or the APK is closed. Therefore, after testing with Companion, the file cannot be overwritten via the APK and vice versa.

you have to save it to shared storage
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
