Blender 2.83 and 2.83.1 crashes rendering with CPU in Cycles

Short version: I'm rendering my Blender Donut animation for the first time, on my brand new 16GB RAM MacBook Pro 2020 w/a 2.6 GHz 6-Core Intel Core i7

Rendering in Cycles and using my CPU (because Macs) and anytime I try to render my animation Blender crashes before it finishes the first frame, which would usually take about 3 minutes (and less than two when I tried to just lower the samples as a solution to this). I was on the second to last release, 2.83, then I updated to the most recent, 2.83.1 It happened in both versions. My memory was taxed to <10% capacity during rendering according to activity monitor, and Blender said it used max 600 MiB memory while rendering the first frame.

The long version: Before it crashes, the render screen says it only used at most 600 MiB memory, so I don't think it could possibly be my RAM causing it to crash. I did install the Radeon RenderPro engine earlier today because I thought that might work better for me but it did not. It made blender slow and unresponsive and tripled my render time, so I switched back to cycles.

As soon as I tried to render a still after switching back, blender crashed. So I quit and shut my computer off for a minute, then came back and it was fine and it didn't crash when I rendered a still.

So I tried to render the animation for the first time and after 99% of Frame 0 it crashed. Downloaded the most recent update of blender, and tried to render it again. It crashed. Lowered the samples by half (60->30) and tried to render, it crashed. My computer gave me the error code after each crash and I can provide them if someone knows what to do with them but it's extremely long and I'm not proficient enough in code to read it.

I sent the file to my boyfriend who is at a similar level of knowledge of blender and it rendered just fine, although he didn't bother throwing in new texture files.

So I don't know what else to do, obviously I'm still pretty new at this. Any help would be very much appreciated. I can provide the file if that's necessary, I'm just not sure how to do that.
