Coredata crash on iOS 13 only

I have an app that is crashing only in iOS13. I don't see this issue on my iOS14 device or the simulator.

Here's the error I get in the console and I included the breakpoint error. The crash is happening on line 14.

Context in environment is not connected to a persistent store coordinator: <NSManagedObjectContext: 0x281050c40>

Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1bf7c5678)

Code Block struct BLAH: View {

    ...
