Unreal Engine Issues and Bug Tracker (UE-76841)

Description

The Editor will crash when rendering a sequence at 7680x7680 with dx12 and ray tracing enabled.

Found in 4.22 CL# 7053642, 4.23 CL# 7208101, 4.24 CL# 7210422

Steps to Reproduce

Open attached project
Open the level sequence
Try to render the sequence out at the resolution 7680x7680

Results:
Crash

Expected:
No crash

Note:
The video driver crashes with no callstack in 4.22 but in 4.23 and 4.24 I get a specific callstack.
