I don't even understand what Star Field is supposed to be. And I don't think Bethesda know either. It's basically what No Man's Sky used to be before they fixed it, yet somehow worse.
Given the fact they knew that fallout TV series was coming out, I do find it a bit baffling that they didn't just make fallout 5. Which would have worked better with the limitations of the engine as well.
After that they could have taken their time to reskill their staff on either a new engine of their own or just a off the shelf option.
2 years to go from pre-production to complete release, and with extensive special effects requirements as well. Na, It may have begun prep work in 2022 but it's been known about longer than that. Pre-production takes a very long time, you have to scout locations, you have to hold auditions, you have to work out schedules, you have to work out your set design and your costume, you have to get the script written. There's a lot before anyone shouts action.
Also that would have been a fair amount of time before that where the studio and Bethesda were negotiating the IP license.
Also I wouldn't be surprised if Covid got in a way of all of that as well. So we really could be looking at 2019 or even 2018 is a start date so it's entirely believable that they weren't that far through production and giving the problems that they would have found by then, they really should have switched gears.
If you're going to reach back into the time period before they hired the writers/showrunners to actually develop a script in early 2022, or selling the rights to Amazon in 2020, then you're talking about a project that was far from certain it would actually get made. Hard to say that they "knew" a tv show was coming before 2022.
I won't lie, they pulled the wool over my eyes with Starfield. I kept waiting for that moment where they brought it all together and suddenly it would be a great game. I was shook when the credits rolled and I hadn't yet found the fun part.
