Why was Concord DoA upon launch?

When the game was released (back in 2024) it barely surpassed 1000 players on steam, eventually the servers were shut down a fortnight after it was released: so the game didn’t even last that long. Development costs were not cheap either, since Sony invested $400,000,000 into the project for it to fall apart upon release, talk about a waste of investors money. Have you played it at the time? If so, what made it a shit game that’s forgotten?
