ssh-agent in wsl2 after restart wsl

[hmz22]

Hello Dears;
I have problem with ssh-add in wsl2 I add this in .profile or .bashrc:

if [ -z "$SSH_AUTH_SOCK" ]; then
   # Check for a currently running instance of the agent
   RUNNING_AGENT="`ps -ax | grep 'ssh-agent -s' | grep -v grep | wc -l | tr -d '[:space:]'`"
   if [ "$RUNNING_AGENT" = "0" ]; then
        # Launch a new instance of the agent
        ssh-agent -s &> $HOME/.ssh/ssh-agent
   fi
   eval `cat $HOME/.ssh/ssh-agent` > /dev/null
   ssh-add $HOME/.ssh/<your ssh key> 2> /dev/null
fi

and it's worked for first time and after restart system or shutdown WSL and re run it ssh-add -l is empty and won't work and I must kill agent and re run WSL because the pid of agent changed and ssh-agent file data don't change e.g pid when run first time is 3412 and when restart WSL and run again pid is 213 but content of ssh-agent file is like this:

SSH_AUTH_SOCK=/tmp/ssh-XdsUS8eespqk/agent.3411; export SSH_AUTH_SOCK;
SSH_AGENT_PID=3412; export SSH_AGENT_PID;
echo Agent pid 3412;

can someone help me for fix it
