Reading file data from a browsed local file

[Taifun]

you are using an Android 11 device
currently the file component only can read from the ASD (and not from a random directory) starting from Android 10
therefore follow this advice

@TIMAI2

The File component could be looking at the ASD..., so you may have to copy the picked file there (ASD) first in order to be able to read it.

this might change after App Inventor targets SDK30...
