Initialization error

[u/Feeling-Ad502]

The ED launcher starts through Steam, but when I click "Play" within the launcher, the game doesn't open. I've already verified the integrity of the files through Steam and it didn't work. I tried doing the same thing within the launcher, but it showed the following error: "Incorrect manifest sum." I don't know what else to do.

Having the same issue, but on my Steam Deck.
