The files is created and stored on the device at /storage/emulated/0/EventData.txt.

It is no longer possible to save a non-media file (e.g. data.txt) in the root dir of the external storage on Android 11+. You MUST use one of the Shared folders (/Documents or /Download) or save it in the ASD.

There are a lot of topics related to this. See also here:

If you use Android <10, try DefaultFileScope, Legacy.

He must set DefaultFileScope to Legacy in any case (Android version).
(Of course this is a bug on Android 11+ as I mentioned countless times.)
