If not, I suppose you could manually add your primary user account with this (might have to use this with sudo):
sysadminctl -secureTokenOn <username> -password - interactive
(note the whitespace between the dash and “interactive”)
you mean:
sudo sysadminctl -secureTokenOn <username> -password - -interactive
Update, I tried that command and got this:
2022-03-19 23:38:17.259 sysadminctl[7050:120302] Operation is not permitted without secure token unlock.
