Project clips stuttering and now unable to render sequence
I have been working on a project pretty constantly over the last few days that have been using screen recordings of Google Earth (which I have come to imagine are pretty sizeable media), and at first, things were working well. I initially started rendering the sequence to facilitate a smoother playback with these heavy clips, but have noticed a brief black frame at the start of one of my clips (where a tiny portion appears unrendered despite being in the middle of a clip), and more recently noticed stutters when clips end (as seen in the provided video below). And now, when I attempt to rerender the sequence, I am met with a message that says it is not possible
I am pretty unfamiliar with nearly every technical aspect of this program, so I apologize preemptively if I have accidentally omitted any pertinent information or if I need to be walked through it slowly.
I am using Adobe Premiere Pro version 22.6.3 (Build 2) on a Macbook with Monterey version 12.6.2
