I'm having the same problem. Made a villager breeder which was working perfectly, being able to break the workstation and change his profession. Upgraded to 1.17 and was working but suddenly for no reason I can find, it's no longer working - villagers can take more than 10 mins to accept the workstation again after breaking it. Checked the number of workstations in nearest chunks and testes by removing them but didn't work. Hope it gets fixed soon.
