Bug very dangerous default behavior

remove this ASAP
already got stuck converting a 20GB project to a non prod version of unity.

 

You can use the cancel button or the cross on the top left, then choose what version of Unity you want to open your project with.

People are not that dumb and click on "Open with..." inconsiderately.

 

It happened another time on the same project so I took some notes that you folks can log as bugs:

1. Unity or Hub some times forgets which version opened it, it's happening in 2020.1, perhaps because the editor was killed during computer shutdown or hardcrashed
2. conversion is the default button! Cancel should be default on non reversible destructive operations.
3. this window takes a long time to appear and since as of late unity takes a very long time to open project, if you multitask, enter can be pressed easily when the infobox steals focus (it shouldn't steal focus, bad practice, modal is local to the app) if you're typing something in a chat then conversion is triggered

A better workflow is to open the full hub and highlight the project and request version choice - explicit - don't assume what we want to do with our projects.
