World Building

Summary

After the most recent update I am no longer able to open one of my projects. The project loads to around 88% then crashes and displays the following error. Another one of my projects when I attempt to rebuild the landscape crashes right away and displays the same error:

Fatal error: [File:D:\build++Fortnite\Sync\Engine\Source\Runtime\RHI\Private\PipelineStateCache.cpp] [Line: 452]
Shader compilation failures are Fatal.

I have tried multiple things to fix this issue and I am unable to open this project I have been working on for a good chunk of time now.

I was able to open my projects on a different system. So it seems to only be an issue with my PC, hoping this information helps.

Thank you, I’ll let them know.

After the last update the project has opened. Everything seems to be running smoothly but if I run into anything I will let you know!
