  export NVM_DIR="$HOME/.nvm"
  [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

You've got the wrong project. Your code is measuring the startup time for nvm-sh. It even says so in the example code.

Furthermore, nvm-windows doesn't load anything because it's not a shim. When you call node/npm, you're calling node.exe directly. The only time nvm-windows does anything is when you run nvm <command>.

What I suspect you're doing is running nvm-sh in WSL. Perhaps that is trying to launch the WSL environment before it runs nvm... I really don't know. It looks like you ran nvm debug in the standard terminal... so technically you ran one program and produced debugging output for a different program.

I'm closing this because it looks like this is an nvm-sh issue or a WSL issue, not an nvm-windows issue.
