I'd be cautious about some of your assumptions.
If you disable UAS then the drive operates slower, at slower speeds they draw less current. Therefore you can't rule out it being a power issue when UAS is enabled. You can achieve the same effect by plugging it into USB2.
Your steam deck power supply is PD, the Pi4 isn't, so the Steam deck will only provide 15W (5V@3A). Even on a Pi5 with PD, the steamdeck is probably not capable of providing more than 3A at 5V, the 45W mode is for 15V output, it appears to have an overall limitation of 3A output regardless of voltage..
However, a power issue normally creates a USB disconnect in the logs, so in this case it might not be a power issue.
