RuntimeError on Windows theme change

[LucasPlacentino]

Problem description

Please describe the issue concisely in here. In case of an error: Walk us through the steps you took to get there. What happened? What did you expect to happen?

Hi,
[What]
Anki throws a runtime error (see logs below) when Windows' theme changes.
[Context]
I set up my Windows theme to automatically change on sunrise and sunset (for light and dark mode), when it does the Anki error popup shows up.
[Info]
This is a non-blocking issue (and nothing seems to be broken when it happens) but is annoying still. I've narrowed it down to ReColor by disabling other add-ons, and it doesn't happen when Anki is launched in safe-mode.
[Details]
I'm running Anki version 25.02.6 (6381f184), on Windows 11 update 24H2 (build 26100.4061), and the automatic theme switcher I use is (open-source) AutoDarkMode version 10.4.2.29 (commit 5922db4)

Thank you!
