Game won`t start

Hi,

got a brand-new GamingPC way above the requirements and BF6 won`t even start... I get the message "game launches (starts?)", Javelin-Anticheat is supposedly being loaded, then a small black window, then shortly a black screen and back I am on the desktop and in the EA-App.

I searched the FAQs and the net, toggled all the right switches in BIOS and the Win-OS and even followed a couple other tips. - nothing works

EA-Support has ignored my (repeated) requests for support for 10 days now. I had expected more.

Anybody have a suggestion?
