Update KB5050021 for version 23H2 has similar issues. In some cases, USB headphones stopped working. The situation is similar in Windows 10 with the latest updates.
After the updates, the Bluetooth headphones still connect but do not play sound. Users also report that they cannot watch YouTube due to an audio rendering error. Reconnecting and resetting Bluetooth does not help.
