I run CI in GitLab, for this I made Runner on my local Windows 11 machine. The git, flutter and dart commands work on the local machine, but in GitLab CI/CD, which is executed on the same local machine, dart and flutter stop seeing git, although git commands are also executed.

Here is the output of the Job execution result:

The same actions are freely performed in the terminal:

flutter doctor

Here is runner config:
