Deleting properly folder

What is the actual behaviour/value?

Trying to delete folder which contains something (there is no possibility to delete non-empty folder) getting error The folder is not empty. After deleting build inside and trying to delete folder (now it is empty) again it gives Couldn't delete $PATH: Permission Denied. After restart PoB folder is gone.
Knowing Windows issues I tried to run PoB as Administrator but nothing changed.

How to reproduce the issue

1. Create a new folder
2. Create and save any build inside folder
3. Try to delete folder
4. Get The folder is not empty message.
5. Delete build from folder
6. Try to delete empty folder
7. Get Couldn't delete $PATH: Permission Denied error.
8. Restart PoB
9. Folder is indeed deleted

Build code

Any build (even empty).

レポートではファイルもテストも指定されていません。まずデスクトップアプリでフォルダーのワークフローを再現し、その後、フォルダーとビルドの削除を処理しているコードを見つけてください。空でないフォルダーの削除が意図した動作に従い、空にしたフォルダーを削除しても権限エラーが報告されず、アプリの再起動も必要なければ完了です。
