Figma unusable

I have been spending half a day trying to make up the mess of the latest Figma update which completely destroyed UI rendering.
I have some nested components logics, because it is more efficient for maintenance, and now all of these nested components do not render properly. 
I tried using "Regenerate all instances" multiple times (which just, weirdly, makes it worse) and also reset and restart the app. 

Nothing to do. I stopped updating everything because all updates destroy the UI.

Please do something. We are spending tons of money on this tool, these type of issues should not happen.
