hi,
please tell use more about your specs - just the APU is not enough ;)
1. disable Win10 auto-driver-install
2. download the latest correct driver - either APU or dGPU
3. install with the "factory-reset" option
test again
ps maybe do a fresh install of Win10 20H2 - as some OEMs use so much bloatware
