HEVC Hardware Accelerated encoding no longer works in Monterey

[nigel415674]

I recently upgraded my 2020 iMac and it no longer allows me to encode to HEVC using Hardware Acceleration (Video Toolbox). I've tried this using ffWorks and a program called VideoProc. I've been using this functionality for 18 months now, and after upgrading the Monterey, it stopped working. Is anyone else having this problem?

I tried downgrading to Big Sur, but the Big Sur installer will not allow me to downgrade so I am looking at other options right now.

My machine specs are:
2020 iMac
3.6 GHz 10-Core Intel Core i9
Cores: 10
Memory: 64 GB
T2 chip
AMD Radeon Pro 5500 XT
