That's a known old issue and should be resolved with v5.1.2 and onwards.

Even before creating issue report there's advise written that only latest version is supported. So have to remember to recheck official website and try newest version before creating new issue reports.

Do I need to upgrade manually?

You're using Windows, so no easy way to do it fully silently or automatically. Download latest installer and it will help to upgrade, isn't complicated at all, just as easy like it was with upgrading previous versions.

But if the update function within the program doesn't work properly, why not remove it entirely?

That's misleadingly written bad idea or question and not appropriate to keep on asking off-topic questions.

There's a Discussion page if really want to ask random questions or share not thoroughly thought ideas instead of writing a proper feature request.

https://github.com/qbittorrent/qBittorrent/discussions

If built-in check for updates is improved with v5.1.2 and isn't working as expected only with certain versions and newer version is more secure and might crash less often, then I see no good reason why it should be removed.

Wishing to remove instead of improving something will make things worse for everyone.

I have really obnoxious constant crashes to desktop without any visible message.
I have several dumps from today.
Using latest 5.1.2 qt6 lt20 build. I've tried 5.2.0 nightly build too, same crash to desktop.
Where do I have to upload memory crash dump files so you can check them.
The worst part is that the torrent progress is not saved and after the crash the torrents start from the beginning.

Before qbitorrent crashes completely the down/up speeds decrease to almost zero and then qbittorent simply exits without any message.
