Can you let me a link for finding Premiere Pro 2021, because the 22nd version doesn't satisfy me. I have to work with Format - QuickTime/Preset - Apple ProRes 422 LT , and there's no audio codec, and I don't like that.
In Format H264 I can't work, because it gives me error 3.
Can you be more specific with your issue? ProRes should export the exact same way in Premiere 22 as it did in Premiere 21. This is a screenshot from AME 2021 (the same options you'd see in Premiere 2021) and with ProRes selected you don't get an option to choose an audio codec, it's always exported as Uncompressed. The second shot is from Premiere's new Export workspace showing the same options (these screenshots are from different files, so the settings are a little different).
