I cant launch Trados 2021

I cant lauch my Trados 2021 (SDL Trados Studio 2021 Freelance Plus 16.2.10.9305). Last time I worked few day ago, everything was ok. Today I receivided SDL package but I could not open it. Then I tried to start the application from my desktop - without success. I saw first window and the application was off, without any error message. I downloaded software from SDL site and tried to reinstall it - the result is the same: launch started and then off, no error message. Thank for any hepl!
