Are CBP officers rejecting ESTAs during time of COVID?
Apparently, if you attempt to fly to the United States from or through a country that is subject to the COVID travel restrictions, the system will automatically cancel the ESTA and indicate to the airline that you may not board the airplane. In that case you will never encounter a CBP official.

Your ESTA is valid for two years, for multiple travels, and neither the date nor the location you used when applying are of relevance.
Aside from potential COVID restrictions (which I don't know), you can fly with it to any place in the US, at any time (within the two years).
