powerlevel10kを入れたときにWARNING文が表示されてしまう

Question

iTerm2をinstallし、zinitを導入して、powerlevel10kを入れたのですが、iTerm起動時に下記のような注意書きが表示されてしまいます。何が原因かわかる方はいらっしゃいますか？

[WARNING]: Console output during zsh initialization detected.

When using Powerlevel10k with instant prompt, console output during zsh
initialization may indicate issues.

You can:

  - Recommended: Change ~/.zshrc so that it does not perform console I/O
    after the instant prompt preamble. See the link below for details.

    * You will not see this error message again.
    * Zsh will start quickly and prompt will update smoothly.

  - Suppress this warning either by running p10k configure or by manually
    defining the following parameter:

      typeset -g POWERLEVEL9K_INSTANT_PROMPT=quiet

    * You will not see this error message again.
    * Zsh will start quickly but prompt will jump down after initialization.

  - Disable instant prompt either by running p10k configure or by manually
    defining the following parameter:

      typeset -g POWERLEVEL9K_INSTANT_PROMPT=off

    * You will not see this error message again.
    * Zsh will start slowly.

  - Do nothing.

    * You will see this error message every time you start zsh.
    * Zsh will start quickly but prompt will jump down after initialization.

.zshrcの中身

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.
