Nvidia 5080 Hardware Encoding not working in VMix Streaming (SOLVED)

I have a new system and have been having issues with VMix hardware encoding for streaming from the beginning. The system functions in OBS perfectly and other software. Specifications: MSI 5080 Suprim CamLink Pro (connected to CPU PCIE LANE) Intel 285k CPU 64GB RAM Latest VMix software Latest Nvidia Drivers Symptoms: - Using VMix FFMPEG/FFMPEG2/FFMPEG6 to stream to any destination with Hardware Encoding ON causes the Stream to fail to start, error given in log: "No NVENC capable devices found". Streaming with Hardware Encoding OFF streams successfully, or when using CPU for hardware encoding. What I have tried: - Checked that VMix sees GPU in Settings - Performance tab - Ensured no other processes are using NVENC - Tried low latency and high performance modes - I tried disabling all hardware encoding in VMix and enabling again - Reinstalling VMix - Reinstalling GPU drivers - Streaming from OBS with hardware encoding (verified it works in OBS) - Recording in VMix MP4 with hardware encoding (verified it works, only streaming doesn't) I tried emailing VMix support and am still working with them, but no resolution after troubleshooting. Does anyone else have a 5080 and having issues with Hardware Encoding to Stream in VMix? LOG: Quote:FFMPEG1.Exited

UPDATE: VMIX Support said it seems only FFMPEG6 is supported by 50-series GPU's. Setting to FFMPEG6 in stream settings allows successful streaming.
