Mykita,
- Have you tried deleting your Intermediate and Saved folders from your project folder?
- Are you using 4.13.1?
- Is your engine from the Epic Games Launcher or is it from GitHub?
This looks like it’s the error:
Failed to start local process for action ("Kan ikke starte prosessen fordi et filnavn ikke er angitt."): -o BatchMode=yes ${CURRENT_USER}@ "cd \"/\" && xcode-select --print-path"
Looking forward to hearing back from you, thanks!
