Looks like I had the same issue with Memories Europa mission, after video it would not load so I switched back to directX12 from 11 tried loading failed. Valadated files again filed 2 but masterful was there this time to place a being to dumb me down so I couldn't see or hear spiriually, while trying to channel to his following what was going wrong. I hexed him and tried re running it failed so I thought why not switch it back to DirectX11 and for some reason it worked. It allowed me to finish the Memories mission's, however I like this game too much for it to be buggy, so hopefully they can get it all squared away.
