yarn is not recognized as a command on git bash in windows

Question

I installed yarn using npm: npm i -g yarn

when I execute the command yarn -v or any other yarn command on cmd or PowerShell it Outputs the Version

But on GitBash it displays: C:\Users\<my_username>\AppData\Roaming\npm/node_modules/node/bin/node: line 1: This: command not found

I even tried Reinstalling Node & Yarn but it still doesn't work.

1 solution I found is that instead of yarn if I use yarn.cmd then it works in GitBash.

But I'm unable to find the reason & the correct solution for this problem. If someone has any Idea please Guide me.
