.UMap crashing project, unsure why

edit: this should really be posted as a question, but unsure if I can change that and it won’t let me repost - apologies

Hi all!

As the title says, my project has a .umap which is causing the project to crash when the map is attempting to load.

iirc the map has been migrated through engine versions, but has worked after the process. Was
also working by removing umap from content folder with project closed and re-adding at runtime, however this workaround no longer works.

The visual studio debugger points to


on crash

I’ve been trawling the logs and not entirely sure what the issues is here, my best guess is a material used in the map has gotten botched somehow.

Any help greatly appreciated! :slight_smile:
