Arkane Austin only made Redfall since Prey, the rest were Arkane Lyon (which didn't close). Allegedly (based on some articles) Redfall started as a pure singleplayer game ala Prey 2017 (and their older titles) but Zenimax and Bethesda wanted to add multiplayer and Games-as-a-service elements because they thought it'd increase the company's value back when they were looking for buyers
Essentially the studio was forced to make a game very different from what they were known for (not just as Arkane but even people who worked there) and wanted to make for reasons outside the game's own merits, which in turn introduced a lot of production issues (they did not have the staff or know-how and had to expand in size) and predictably ended up a mess.
