It seems that NahimicOSD has been causing a lot of troubles. I believe it comes from the audio driver (download file from Asus website: DRV_Audio_RTK_SZ_Nahimi_TSD_W10_64_VER6018666_20190611R). How can I remove it completely.
I unistalled all Realtek Audio Driver under Device Manager even with the deleting file option, but NahimicOSD is still causing problems.
Any tip will be greatly appreciated.
