Sometimes the Moon can seem to disappear briefly at night when clouds flow in front of it for a bit. The clouds may not be easily visible, especially when the Moon is not full (and therefore there isn’t as much moonlight), and it makes it seem as the Moon is disappearing on its own. Or, if the Moon is close to the horizon, it may be blocked temporarily by something such as a far-off bridge or tree that might not have been easily visible at night. If you were viewing the Moon over a body of water, sometimes a passing ship may obscure it for a moment.
In Eastern Daylight time in Boston, Massachusetts, on July 23, 2023, the Moon (a waxing crescent) rose at about 11 am in the east, crossed the meridian at about 5:10 pm, and set in the west at about 11:09 pm. In Pacific Daylight time in Seattle, Washington, it rose at about 11:34 am, crossed the meridian at about 5:40 pm, and set at about 11:34 pm. So, for the period that you mentioned, between 10:50 and 11:25, the Moon was setting, and likely somewhat close to the horizon, so it may have been obscured for just a few minutes by moving clouds (or a passing ship), or by an object on the horizon briefly as the Moon descended behind it. Perhaps that is what happened? Hope this helps!
