Why didn't Starfleet build more of the USS Prometheus?

I just saw the episode with that ship, ep 14 of season 4 and it's a good episode but why in the heck didn't Starfleet not keep the plans and build more of these after the war, they seemed like a really neat ship that isn't your typical Starfleet ship.

There were some unnamed ones that were referenced in Prodigy and during the Battle of Procyon V.

Plus there are a number of these ships in the novels and games. I'm part of a ship that is this class in Starfleet International, also.

How do you know they didn’t?

Because it seems a design not many people talk about and isn't really shown in other media beyond games

The last time we saw a Prometheus class starship was the series finale of Voyager in 2001. Other than Star Trek: Nemesis which premiered a year after that in 2002, we never saw the 24th century of the prime universe again for the next 18 years until Star Trek: Picard in 2020. In-universe, the time between Endgame (2378) and the start of PIC (2399) was 21 years. I'm sure in that 21-year span of time, Starfleet produced many Prometheus class ships; we just didn't see them on screen because there was no prime universe 24th century Trek on TV at that time.

Wasn't there one in Prodigy?

From what I understand, that was a production error. The flashbacks we see were supposed to have shown the Protostar, not a Prometheus class ship. And this error actually happened twice. I could be wrong about that, though.

According to Memory Alpha's Prometheus-class page, the Prometheus-class appears in:
Voyager 4-14 "Message in a Bottle" and "Endgame" (likely the Prometheus's 2nd appearance)
Enterprise 3-18 "Azati Prime" (Prometheus-class ships are seen zooming past the Ent-J window)
Prodigy 1-16 "Preludes" (Prometheus-class ship cameo)

From what I understand, that was a production error. The flashbacks we see were supposed to have shown the Protostar, not a Prometheus class ship. And this error actually happened twice. I could be wrong about that, though.

Not a production error. A Prometheus-class starship presumably made first contact with the Solum after the Protostar accidentally jumped into the future.

Spoiler: Prodigy - Season 2 (all episodes)

By the end of the series, this was replaced with the Infinity and Voyager-A due to time travel shenanigans.
