Problem Description

We are seeing an issue in debug on larger fetch requests > 10mb (release is fine).

Issue was not present in prior version and also not present in android or ios.

Error being thrown is Access violation writing location at: WinRTHttpResource.cpp Line 398

We had an issue a few years back that had a hard cap at 10mb however that doesn't seem the be the issue this time.

Steps To Reproduce

Create a new project, fetch a data packet greater than 10mb.

Expected Results

Fetch succeeds

@JunielKatarn Any immediate ideas?

[chrisglein]

Here's the relevant PR for the 10MB issue: https://github.com/microsoft/react-native-windows/pull/10885 But seems like you're hitting some problem with the new solution.

[jbcullis]

@chrisglein yeah, this is definitely different.

Only impacts dev this time so it's seems like it's a memory or space allocation capacity issue in dev whereas previously it was to do with the request size.
