Crash when Switching Build Platform to MacOS

We've been developing a project with Unity 2019.2.10f1 and everything has been going great until today. I tried to switch the Builder Settings to MacOS and as soon as it finishes "Determining assets that need to be reimported for target platform" it crashes:

I checked the editor log and this is the output:

Any idea what the heck is going on? It just started happening suddenly, does not happen when I try to switch to Linux, and does not happen with other unity projects?

I already tried deleting the GI cache and Library inside our project folder but no dice :/
