Render and preview stops at a certain point
I've been working on trying to render a project for days now, but both the preview and render stops at certain points (I tried to render the edit in pieces but it seemed to get stuck at multiple places). I've tried many things; changed my rendering to mercury software only, lowered my motion tile to 300, playing around with the "secret" tab in preferences, purged my cache and memory, but nothing seems to work. Everytime it gets stuck, the whole preview is unresponsive so I have to force quit after effects.
I use macOS Monterey version 12.1, with a graphics card of Intel Iris Plus Graphics 645. Though I don't think the problem is in my laptop/graphics card, since I gave my project file to my friend so he could try to render it, but he encountered the same problem.
I don't have too many effects, it's just a simple transition edit. I used some effects from the sapphire plugin as well.
Any advice would be much appreciated.
