I fixed the problem. The problem caused by inadequate directory path.
The artiq directory was installed in :c\Users[user_name]\miniconda3\envs[env_name]\site-pakages
and I moved the artiq directory to :c\Users[user_name]\miniconda3\envs[env_name]\lib\site-pakages
As a result, the dashboard runs well!
Thank you for your attention.
