Denon MCX8000 displays Freeze Serato and Standone

Hello guys, Before almost 1 year i bought Denon MCX8000, Perfectly controller, I’m inlove, 8 months It worked perfect, but after 4 months ago it starts to freeze displays with Serato and only in standalone mode. I’ve updated everything but it still freeze, I have powerfull laptop and good cables. I send it to the shop where i bought, but no help. Any ideas? Thank you
