Problem solved pp 23.5 (multicam and audio track mixer) VIDEO

Even from the last few Pp 23.3 - 23.4 and even the latest version 23.5 multicam does not work properly... in this video there are 3 projects, one from 2014, the second from 2021, the third from 2023... all multicam... Ppro opens the 2014 project without errors in multicam, the multicam window appears immediately... while the newer projects 2021, 2023 will not open in multicam. I found a solution to get multicam, but there is also a problem with the Audio track mixer panel... while it is on, the timeline (CTI) is standing still or jumping from place to place, and it is impossible to stretch the timeline, when the panel is turned off, the timeline is smooth and without stuttering even when it is stretched to the maximum, it is very fluid and can stop wherever you want... that was not possible before v23.5 and thank you Adobe for listening to us... the multicamera problem remains as well as the Audio track mixer panel... ..... .watch the video for multicam solution and Audio track mixer panel problem...thanks
