Kind of glad to know that I am not alone I seeing this issue. I have found that if you safely remove your eGPU using the Windows safely eject button. Remove the eGPU cable (I am using thunderbolt 3) then reboot it works.

If you then end up with an error code 12 issue then try my solution referred to in post: "Code 12 on XPS 13 9380" saves me repeating.

Finally good luck and let me know how you get on.

iGPU: UHD 620 | eGPU: RX Vega 56 | Asus XG Station Pro | Thunderbolt 3 (15D9) : NVM 44.00

It seems that the plague has come back since my motherboard got replaced. My eGPU is working on boot every time but my CPU is throttled back to all cores at 0.40Ghz. So machine is grinding so slow.

I have tried all my previous tricks and not one is shifting the CPU limiter. If I uninstall all of my audio devices the cpu climbs back up but once they are all back its stuck at 0.40Gz again. 

If you get any luck with yours please let me know.

Regards,

Did you ever manage to get to the bottom of your issue? As I must of got past mine by luck and my CPU limitation seems to continue.

regards, James

Thank you for coming back to me. I will need to use the iGPU whether eGPU is not connected, but it does give me a focus in direction towards troubleshooting. So thank you.
