Refresh of podcast failing on Windows 10

[artisticforge .]

Hello

I am not a regular user of Windows any version.
I have get_iplayer-2.95 installed on Windows 10 on a toshiba laptop.

I have noticed yesterday and today that podcasts are not being refreshed.
the podcast.cache file is basically empty except for the field header line.

I have verified that the get_iplayer.pl and get-iplayer on Devuan
Linux are the same source.

podcast refresh works on MacOSX and Linux. Not on Windows 10.

the log file for Linux contains:
INFO: Search args: '.*'
INFO: Got 27054 file cache entries for podcast
INFO: Getting podcast Index Feeds

the log file for Windows contains:

When I copy the linux podcast.cache file to Windows-10 and update
the podcast.cache is overwritten with an empty file.

Hints would be welcomed.
