What platform are you running Path of Building on?

Windows

How is Path of Building expected to behave?

When I open PoB it should update, and when I close the application it should completely stop.
Both of these fail.

How does Path of Building behave?

When I open PoB the download starts and it always gets stuck after a couple of files sometimes "Downloading 1/60", sometimes "Downloading 8/60", etc.
When I close the app it stays open in the background consuming 15% of my CPU and I have to end the task manually through my Task Manager.

Every time I open and close PoB a new instance of the app remains open on the background consuming another 15% CPU adding up each time and eventually slowing my computer to a crawl.
(This has been happening for years and I've always had to uninstall and manually install every new update)

It happens on both the regular version and the portable version.
Added exceptions on the firewall and my antivirus (Malwarebytes), still no luck.

How to reproduce the issue

1. Open PoB
2. Wait until it tries to download the update
3. Close PoB
4. Repeat...

まず、記載された手順に従って Windows updater とシャットダウンの動作を再現し、通常版とポータブル版の両方を確認します。ダウンロードが途中で停止する理由と、終了したインスタンスが CPU を使い続ける理由を調査します。更新が完了し、Path of Building を閉じた後にバックグラウンドプロセスが残らなければ完了です。
