New trouble from today

Hi everybody. Today I met with problem with comodo dragon.

It is first time when I met with problem. After opening browser - I saw clean window without previous session (I had mayby 15 or more tabs). After a few seconds, the browser closed itself.
Now it happens all time, I open browser see clean windows and button with recover previous session but it does’t work. After a few seconds browser closing.

I download new installer and reinstall browser and reboot pc - but it does’t help.

Help please.
