This message you will see when you are upgrading a project that contains 'old' Substance graph data that will need to be updated. This is because 4.24+ we switched from USubstanceTexture2Ds to using the Unreal standard of UTexture2Ds. This requires the 'updating' or regenerating of the Substance textures in the project.

Problems arise when trying to update the Substance textures. If the Substance sbsar files/textures are large or there is a large amount of them, this seems to cause problems where it will run out of memory during the update process and then crash.

Did the crash happen during the update process? Or did it happen when you get back in the Editor? If the crash occurred during the update process, then there will be both updated and non-updated Substance textures in your project and this can cause crashes.
