Can you share the output of a few lines of
powershell (C:/Users/adminuser/AppData/Local/Programs/Python/Python37-32/Scripts/gcalcli --nocolor agenda --details all --tsv --nodeclined)
Maybe on Windows the tab separated values are coming in a different order? (Unlikely, but I am having trouble coming up with plausible explanations). I’ll try to spin up my Windows laptop this weekend and check things out there too if we don’t figure out before then.
