hi,
your iGPU is GCN1.1 - so the newest driver should work fine
BUT do you have a dGPU? what is your Laptop?
1. disable Win10 auto-driver-install
2. update Win10 to 20H2
3. reboot and delete C:/AMD
4. run DDU in safe-mode - clean old driver
5a. install 20.12.1 (IF YOU HAVE NO dGPU - only APU)
5b. if you have dGPU = tell us which one ;)
