The GoogleDiff library doesn't feel powerful enough to perform the diff on a 2.5 Mb text body. As a result, it crashed.

I'd propose the following:

If the body is huge (>= 1Mb for example), Proxyman might not perform the diff. Instead, it shows the user to use a different app for diffing, e.g FileMerge from Xcode => Avoid crash
Trimming the body if it's bigger than 1 MB.

@novitae you can try this Beta build: https://download.proxyman.io/beta/Proxyman_4.2.1_New_Diff_v2.dmg

I completely redesign the diff view, it can handle a large JSON file 👍
