Unknown cook error, urgent help?
Please try what Crydrop has suggested. If that does not work, please look over your blueprints and any code within your project to ensure they're all firing correctly. If you are able to get a bit further but run into another issue, please upload your new logs as a .txt file as before.

Hey Popacosmin, I Had a similar problem and it was because of the Substance Plugin, so disable any foreign plugin and restart it if not, Try to Refresh your blueprint then make sure that the global default server game mode is not set to NONE ( match it with the one you picked in the Default GameMode) in your maps & modes tab from the project settings then Restart your Computer and give it another try! but it seems from the log that you have to delete Config, Saved and Intermediate folders from your game folder. But it's a risky step, should always backup your stuff.
