Please help 😞 my husband can’t play the game now.

Since the latest maintenance my husband can no longer verify the game files on Steam and the game actually deleted itself after stopping at 100% and crashing. He redownloaded it but when he logs in, he’s just stuck in the loading screen. He can see the chat and his character is technically logged in on my screen but he’s not there.

I’ve heard this is a problem Steam has in general with games but it’s never actually broken his games before like this. Are the files corrupted from the files not fully verifying now? I thought a redownload would fix it but it didn’t work.
