Error when changing node version with nvm

installed nvm latest version 1.1.9 and then installed node 16.16.0

i changed the node version as follows, but it failed due to permission issue

BASH
$ nvm ls

  * 12.18.0 (Currently using 64-bit executable)
    16.16.0

$ nvm use 16.16.0
exit status 5: Access denied.

eXIT STATUS 1: Cannot create file because it already exists.

i googled it and it says I need to run cmd (git bash) as administrator.

Then vscode says...?

unlike Mac, if you change the node version with nvm use after opening git bash as administrator, the setting will remain the same in all subsequent git bash (on Mac, you have to change the node version with nvm use every time you open the terminal)
