Expired certificate completely breaks macOS Logitech apps, user customizations

If you're a Mac user with Logitech accessories and you've noticed that your settings and customizations seem to have gone away this week, you're not alone.
The company's Logi Options+ and G Hub apps for macOS abruptly stopped functioning on Monday, refusing to launch and reverting all accessories' settings to their built-in defaults.
The culprit, according to both a Logitech support page and Reddit posts from Logitech Head of Global Marketing Joe Santucci, was a security certificate that was inadvertently allowed to expire, rendering both apps non-functional.
