App crashes on line 0 of file with EXC_CRASH (SIGABRT)

Recently, my app gets many crashes (200+) in production like this one. The issue seems to come from main + 40 (RoundedCellViewHeader.swift:0) (this line is present in all crash files) but I don't get it, since the line number is 0.

My app currently contains a mix of SwiftUI and UIKit files, but the issue seems to come from the UIKit part, though I don't think it was happening before. Opening the crash in the project simply shows the crash on @main in the main app file.

Here's the RoundedCellViewHeader file for reference, though I'm not sure the issue really comes from there.

What does this crash log mean?

The other interesting line is:

closure #1 in KitRendererCommon(_:) + 168 (UIKitApp.swift:37)

Xcode shows me this line as the culprit of the crash. Is there a bug with the mix of UIKit and SwiftUI code?
