Did you try uninstalling before re-installing as the error recommended?

Also came across this while attempting to upgrade nix.

Attempting the uninstall step exits with the same error, but suggests running uninstall with the older version which was used for original installation.

Using the older version was difficult, presumably there are all sort of improvements and bug fixes since then. After a restart, things were pretty broken, requiring manually deleting the Nix store disk (macOS). Only then did the install work using the newer installer.

TBH, it's a pretty scary process to have to do just because some new required fields in a config file I never knew existed are causing panics. Thankfully, all the necessary guidance was provided by error cause messages, so nice job on those 👍🏻
