I have started to investigate the failures.

I checked the log and it was giving error:

/src/bin/pg_validatebackup/tmp_check/t_002_algorithm_master_data/backup/none
--manifest-checksum none --no-sync
\tmp_install\bin\pg_basebackup.EXE: illegal option -- manifest-checksum

It seems the option to be used should be --manifest-checksums.  The
attached patch fixes this problem for me.

The error message for the above failure is:
pg_validatebackup: fatal: could not parse backup manifest: both
pathname and encoded pathname

I don't know at this stage what could cause this?  Any pointers?

Attached are logs of failed runs (regression.tar.gz).
