"AAPL,slot-name" property breaks hardware HEVC encoder on Big Sur #39

Describe the bug
After trying (and failing) to encode several projects using the HEVC codec in Compressor and Final Cut Pro, I saw that the apps didn't even recognize the hardware HEVC encoder. Once I verified that VTEncoderInfo also fails to find the HW HEVC encoder, I found this post which said removing the "AAPL,slot-name" property in the config.plist fixes the issue. Sure enough, removing the key makes the encoder work again (the apps launch a lot faster too :).

This is the key in question:
