I had Omen 16 (Ryzen 9 5900HX, 16 GB of memory, Radeon RX 6600M)
idk if this going to work, but it was my last best shot :
*be sure you have already download your driver from your laptop manufacturer first
1. Install win 10, after that don't let it connect to any network/internet
2. disable any windows/driver update immediately , see here

3. Install your driver
4. Pray
5. Restart your PC
if it works good, wait a whole day or three day, still working? good. Make a restore point.
sometimes ddu just don't help (in my case)
** some tried to suggest installing the PRO version of the driver but it just don't work for me, maybe try that first and see what happen
