Stuck in Clap Trap Screen and i have DX11

Hi Guys, i have the problem, that the clap trap screen is loading forever and i have DX11!!!
2 Days Ago it worked but no it doesnt… can anyone help me? And i already took a ticket but i think i wont get an answer…

i had the same problem. i got it to work as i disabled any Surround sound option in windows 10 f.e. Dolby Atmos or Microsoft Sonic Surround)

Let me know if it works…
