[BUG] Upon quit, error message RuntimeError: Internal C++ object (DlThread) already deleted. occurs.

Describe the bug

I am on Artix GNU/Linux (rolling release).
Python version: 3.13.1.

I am running a git build from this repository; git checkout at commit cfbd680, built according to this recipe.

I purchased via the Epic Games Store website the game "Manifold Garden" and did download it via "Rare" (I checked the box "download only").

After download, I encountered a popup message as reported in #527, and now when I want to quit "Rare" I get a popup saying

Traceback (most recent call last):
  File "/usr/lib/python3.13/site-packages/rare/components/main_window.py", line 260, in closeEvent
    self.tab_widget.downloads_tab.stop_download(omit_queue=True)

~/.cache/Rare/Rare/logs is empty, the terminal from where I did start rare shows

[...]
Error calling Python override of QMainWindow::closeEvent(): [RareException] CRITICAL: Traceback (most recent call last):

(The terminal output which I skipped can be seen in #527.)

Regards!

This is likely a result of the previous failure.
