LazyVStack crashing widget preview

I have a simple widget with a LazyVStack containing a foreach. The preview crashes, but when I run the widget on device it works.

I get the following error when trying to use LazyVStack.

Code Block 
RemoteHumanReadableError: Failed to update preview.
The preview process appears to have crashed.
Error encountered when sending 'fetchTimeline' message to agent.
==================================
|  RemoteHumanReadableError: The operation couldn’t be completed. (BSServiceConnectionErrorDomain error 3.)

|  BSServiceConnectionErrorDomain (3):
|  ==BSErrorCodeDescription: OperationFailed

I can simply change the LazyVStack to a VStack and the preview works.

My code looks like this:

Code Block 
struct MediumMarketsWidgetView: View {
    let tokenContracts: [TokenContract]
    var body: some View {
        LazyVStack {
            ForEach(tokenContracts) { tokenContract in
                HStack {
                    VStack(alignment: .leading) {
                        Text(tokenContract.symbol.name)
                            .font(Font.caption.smallCaps().weight(.bold))
                        Text(tokenContract.name)
                            .font(Font.caption2)
                    }
                    Spacer()
                    VStack(alignment: .trailing) {
                        Text(tokenContract.currencyRateFormatted())
                            .font(Font.caption.smallCaps().weight(.bold))
                        Text(tokenContract.priceChangePercentFormatted() ?? "%0.00")
                            .font(Font.caption2.weight(.bold))
                            .foregroundColor(Color(tokenContract.priceChangePercent ?? Double.zero < 0 ? "Danger" : "Success"))
                    }
                }
                .foregroundColor(.white)
            }
        }
        .padding(16)
    }
}
