Nvidia NVENC cannot be found in Vegas 20 but active in 19

Hello. I am trying to render using Nvidia hardware acceleration in Magix Vegas 20 (build 403) but NVENC is not active. On the other hand, when I render in Vegas 19 it is working fine. I upgraded the video drivers to the latest version. I also tried with Voukoder 13.1 Thank you for any suggestions.
