There are no lang packs for 22631. 22631 itself is 22621 with enablement package applied. So the lang packs you need are for 22621. You must integrate them before any other package/update. You can check W10MUI from abbodi. https://forums.mydigitallife.net/th...on-automated-batch-script.68791/#post-1217467 The respective folders for the different lang packs have very detailed lists for each supported build. Check them.
