Project Crash Unreal 4.27.2

I’ve been working on this for about a month. Added foliage and streaks appeared on Viewport. I Saved and Closed. Now project will not open. (have I overwhelmed my GPU?) Error Message:
Fatal error:[File:/Users/build/Build/++UE4/Sync/Engine/Source/Runtime/Apple/MetalRHI/Private/MetalCommandList.cpp] [Line: 176] Command Buffer Prologue WholeScene split0 4088x4088 Failed with Timeout Error! Error Domain: MTLCommandBufferErrorDomain Code: 2 Description Caused GPU Timeout Error (IOAF code 2) Unknown Unknown

Is there any way to find the code to delete the assets that seem to have UE and GPU not working??? Or any other way to recover the project??

I was able to open a “copy” in 5.0.1
