Premiere 2020 "The hardware code is not available"

Do you have an Intel CPU that also has integrated Intel HD, UHD or Iris Graphics? If so, that is what the hardware encoding setting refers to. You see, Premiere Pro 2019 and 2020 versions up to and including 14.1 currently support only the CPU-embedded Intel graphics for the QuickSync hardware encoding feature. A beta 14.2 version of Premiere Pro, which is available to Creative Cloud subscribers via the "Beta Apps" section of the Creative Cloud desktop app, supports Nvidia's NVENC and AMD's VCE (both of which require higher-end discrete GPUs using chips from those two companies) in addition to QuickSync. And based on testing, the NVENC performance from a Pascal GPU such as your GTX 1050 is barely faster than the QuickSync performance is from a 7th-Generation i7-7700 series CPU. Newer Turing GPUs such as a GTX 1660 SUPER have a much more robust NVENC feature than the older Pascal GPUs do.

And if you do have a compatible Intel CPU with compatible Intel graphics, and if "Hardware encoding" is still unavilable, then the integrated Intel graphics is disabled by default when a discrete graphics card is installed. In this case, then you MUST force-enable the integrated Intel graphics in the BIOS/EFI setup with the discrete GPU already enabled and connected. However, you cannot do that at all with many big-name-brand OEM computers as they provide no oprtion at all whatsoever to enable or disable the integrated Intel graphics in their BIOS/EFI setup, and some of the gaming computers from those companies also completely omit video outs on their motherboards (which automatically and permanently disables integrated graphics, and therefore QuickSync).

So, in all official releases of Premiere Pro, you cannot have hardware encoding at all if you have a CPU platform that requires a discrete GPU just to even run at all, or if you do not have a compatible Intel CPU.

Try updating or rolling back your graphics driver directly from the video card manufacturer’s site.
