git hitting an error :- error: cannot delete branch 'main' used by worktree at 'C:/work/python/langchain-tool'

While trying to delete my main branch i ran into this error. There are many possible solution. One of them could be this

cd "C:/work/python/langchain-tool"

git worktree list # see the work tree

git switch master # or any other branch

Then try to remove it

git branch -d main
