Unfortunately I don’t have a solution, however to improve the quality of your post I’d recommend replacing your logs screenshot with a text extract of the logs, use the </> Preformatted text block in the editor to enclose your logs for better readability. Screenshots are harder to read and don’t include the full information available

Also please include what Tutor version you’re running!

$ tutor --version
tutor, version 19.0.2
