Studio starts, locks and then closes down

This is new to me. After Studio is started and I select a project to open its files, either nothing happens (I cannot affect Studio in any way) or the Window cirkle (something is going on) starts and keeps going. In both cases, after a while Studio closes down.

It does not matter which project I select.

I have tried repairing the program; it did not help. (Restarting the computer of course does not help either.)

What to do? Unistall and reinstall?
