Hey, did you find out what was causing the error ?
I’m having the same while building on Android

Same error, i disabled Virtual Texturing from the project settings, also deleted all virtual textures and virtual textures materials also deleted the build data of the level because it has virtual lightmaps i guess, after that the cook works again
