CORE V1 with BLADE STEALTH late 2019

Hey Razer Community, im in big trouble i work as creativ producer and my gear is not working how it should. I got big issues with the core v1 and geforce 1660. micro freezes going to hard resets. i try some reinstall drivers also thunderbolt. from the intel site. only new thing i got now an thunderbolt error at the start with "ready to deinstall..." if iput the monitor to the laptop everything works fine but with the core x i got the freeze. i need help, i was so happy with my blade stealth but i need the usbc slot for harddrive not for my monitor.... greets from a tired razer fan
