My .zshrc file is executed twice each time, what are the possible reasons?

Question

I set zsh theme to "random" but I found that everytime I open a new WSL window the theme will change twice, which means my .zshrc file was executed twice every time.

I am using WSL2 now and I am also using oh my zsh.

I tried source .zshrc and the theme only changed once so I think the file itself maybe not the problem.

My .zprofile file is empty.

I am wondering how can I find the reason and what is the solution.

BTW, here is my .zshrc file

zmodload zsh/zprof

# If you come from bash you might have to change your $PATH.
export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH="$HOME/.oh-my-zsh"

# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="random"

# Set list of themes to pick from when loading at random
# Setting this variable when ZSH_THEME=random will cause zsh to load
# a theme from this variable instead of looking in $ZSH/themes/
# If set to an empty array, this variable will have no effect.
# ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

# COMPLETION_WAITING_DOTS="true"
