Why did Premiere show me this "Reset options" dialog popup upon open?

Wondering if anyone can provide some insight into what this reset options window is, and why it suddenly appeared when launching Adobe Premiere Pro.

I opened Premiere the way I normally do, but instead of going straight into the app, I got this popup asking about resetting preferences, media cache, plugin cache, etc.

I canceled out of it, opened my project normally, and everything seems completely fine.

The only thing that was different during this launch was that I had just connected a few external monitors through a new Anker dock before opening Premiere.

Has anyone seen this appear randomly? Is this usually triggered by a crash, a startup key combo, hardware/display changes, or something else?

Screenshot attached.
