As others have said, it is worth trying to reduce the program to the
minimal version which reproduces your problem
(and then publishing it on https://go.dev/play/ ).

Perhaps explicitly capture the error value? That is,
result, err := GetAsOr[MyObj](services.GetServiceOr())
Alternatively, if you don't care if there is an error replace "err" with
"_" to make that clear.

In your reply to the request for `go env` output you say "For all of the

the native Windows Go toolchain from WSL. I would not expect that to work
