What did you do?
cd project
go run .
The same thing happens with go build ..
What did you expect to see?
My program running the same way it did on 1.20
What did you see instead?
# gitlab.com/<org>/<repo>/<project>

I have confirmed that a simple hello world program does work so there must be something specific to the code or project environment.
I searched for the same issue and found #61060 but this seemed too different to lump in with that, and it's happening on the latest release.
