I have pretty much given up using Starlnk. My daughter and granddaughter were here a few weeks ago and had brought her Xbox and connected through the Starlink. I watched the progress line as she tried to download a large file. It started out fast, but at about 33% it started to slow down. it was like somebody was turning off a faucet. By the time it got to 50% the data had stopped flowing. Tried it three times and failed. Switched to the local wireless ISP and it downloaded it flawlessly. It was initially a bit slower, but by the time it got to 25% it was obviously faster than Starlink at that point.
I've had the same problem streaming videos. After a while Starlink throttles the feed and I end up trying to watch an HD video on an 4K TV in 480p.
