hey Elringus-
According to the VS log provided, it seems that there are a few assets referencing the WhiteCapsule material but are unable to find it. If this material has been deleted, please try fixing the redirectors for the project. You can do this by right clicking on the Content folder in the Content Browser and selecting the option for “Fix up redirectors in Folder.” If you are still having this crash occur after, please provide the project logs (in the Saved/Logs folder of the project directory) and the callstack / machine ID from the crash reporter window.
