Try and redefine the ssh url for remote origin:
git remote set-url origin git@github.com:lut/EvolutionApp.git
And try again.
Only git remote set-url can change an existing remote URL (as opposed to git remote add, to add a new remote name and URL)
Here, the issue was the URL of the existing remote ‘origin‘, EvolutionApp: it needed to be replaced by a valid one.
Using git config url."ssh://git@github.com/".insteadOf https://github.com/ would not have helped, considering there was no HTTPS URL in the first place.
