I've looked in Windows Event Viewer for some clues on the error. This is what I found:
Faulting application name: ForzaHorizon4.exe, version: 0.0.0.0, time stamp: 0x5e8e30ad
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000

Faulting application path: C:\Program Files\WindowsApps\Microsoft.SunriseBaseGame_1.410.986.2_x64__8wekyb3d8bbwe\ForzaHorizon4.exe
Faulting module path: unknown

After googling myself silly, I couldn't find any of the suggested fixes for this error to work. I've tried the following:
1) Reset the game from appstore
2) Reinstall the game, twice, oncve to C: and again to a secondary
3) I've tried changing file permissions from various suggestions on the WinApps ffolder, but that didn't work
4) I reinstalled Windows much to my annoyance
5) I've tried this XBOX network fix suggested
6) I've run sfc /scannow as admin, no faults found
7) I've run chkdsk, some items repaired, but didn't fix FH4
8) I've reinstalled and updated ALL drivers
9) I specifically removed Overlay apps (Gefforce now, Discord, Fraps, etc.)
10) I removed all overclocking software (EVGA x1)
10) I set BIOS to default
11) I re-seated memory and ran memtest
12) I checked all temps using HWINFO64
Build spec: i9900k, Asus Code Mobo, Asus 2080ti OC, 32gb G.Skill DDR4, 1TB Samsung 960 nvme
I've been at it for roughly three consecutive days now :(
What frustrates me is that a large number of people are getting the exact same error in event viewer. No fixes confirmed however.
For context, COD MW works 100% for hours on end. So does Overwatch, Doom Eternal and Forza 7.
FH4 used to work like a peach for months on end, and with no user side change just stopped working a couple of days ago. I played last week still.
I'll post the official response from the support team on the detailed ticket I opened. See below. I managed to get mine working before I got the response by doing a full PC wipe and reinstall, so can;t validate if any of the below fixed the issue. That being said, I am running an ASUS board, and I don't have Sonic Audio installed currently. Good luck out there.
