Gforth for Android can't unpack its files or read .gforthrc

Just installed Gforth on a reconditioned Moto G4 (Android 7).  On startup, Gforth pops up a box, "Unpacking files" with a spinner.  In that same box, it reports, "error: no space left".


There's 3 problems:

1: The box goes away very quickly, I barely have time to read the error (and I'm a fast reader)

2: The lack of space is not true, there's 8.1GB free

3: It seems reading is blocked too, because I manually made /sdcard/gforth/home/.gforthrc and it doesn't read it.


#3 is a severe problem for my usage.  If #2 means it can't write files at all, that will be a severe problem in the future.


Possibly related to a report 2 months ago, "[gforth] Android regression on no external SD", but mine doesn't freeze.
