The amount of commercial games that used (and still does actually) Flash is much higher than many could believe. Jackbox is probably one that many here have played in the past few years. Some games used it only for UI, like Borderlands.

For context, most of these games use(d) a Flash derivative called Scaleform for their GUIs: https://en.wikipedia.org/wiki/Scaleform_GFx — it's discontinued now but was indeed hugely popular.

A lot of games today use an HTML-powered UI library from Coherent Labs which can still be authored using Adobe Animate (i.e. what the Flash editor turned into): https://coherent-labs.com/

World of tanks used Flash-based tech for game UIs as well.

PS At least that was the case 9-10 years ago when I was involved.

Scaleform - it came with the big world engine

Did it? I remember it was something Adobe, suspected Adobe Air.

Anyways, the client ui team definitely used Actionscript, which I had to read from time to time as a server-side dev.
