Livebook: Failed to connect runtime - Elixir terminated unexpectedly

I’ve installed livebook by livebook_websetup.exe, but I can’t connect to Elixir runtime in livebook with Elixir Standalone on my Windows laptop.

once I click evaluate or Connect button, it shows:

Failed to connect runtime - Elixir terminated unexpectedly, please check the terminal for errors.

I don’t know what to do, I started it by clicking desktop ico…
Anyone can help? Any operations I should try or some settings I should check?
