This is what I just found out about macro problems/issues:
WIN10 Home Premium 20H21 on HDD:
WP X3 works pefectly (enable macros, repair macro path yes). Yes, old – but last UI version in German so I must not translate calendar data (!).
WP 2020 shows macro bug: in settings menu exchangin Sunday/Monday results in Mondays on all (!) seven days of the week.
WIN 10 Pro 20H21 on SSD:
WP X3 no check boxes, no settings menu; starts with openening calendar of 1997 (!).
WP 2020 shows the same Sunday/Monday-bug.
IMHO my conclusion is: It's a MS-WIN10-Update-issue (who wonders?!).
