Timeline cannot be previewed, motion graphics unknown error
In the past week, pr has had two major issues that have devastated me. The first is that it is often impossible to preview the timeline picture in real time, and the sound can be played normally, but the real-time picture is in a black screen state, and in any case, the sound is only played, and the picture will not appear. The second is that the dynamic graph is unknown error and cannot be used. I tried to reset the preferences once and it would become normal, but the problem would come up again the next time. This makes pr almost impossible to run smoothly. I use the latest mac system and sonoma 14.3.1.pr is also the latest 24.1.
