Premiere is essentially not working on one of my projects..anyone else having trouble?

I have a video that is due and I'm unable to do any edits to the color in particular without it lagging and or just not working. I was working earlier and everything was working smoothly.. then as I went to work on the color and even adjust the crop on some of the clips, my timeline essentially froze. If I wait about a minute the updates may show up but that isn't really realistic.  I opened another project and the coloring was ok with that but it wouldn't work on this one. I tried to make a copy of the timeline/project and it doesn't make a difference. I am so close to being done but can't be done until my color and such has been adjusted.  Also, it appears that premiere isn't making the most of my CPU/GPU which is frustrating. I just feel so discouraged right now


I'm pretty sure that there is something wrong with the premier app itself because Here is what I am editing on : 2024 Macbook Pro M3 Pro chip with 12‑core CPU, 18‑core GPU, 16‑core Neural Engine, 36GB unified memory, and 512GB SSD storage.. 


Here is what I have done already --
