impossible to trade with the villager

after upgrading to version 1.14.3
in my village some villagers
(mostly farmer) at various levels of experience have become unmanageable
since at least 1 of the villagers in the village does not open the inventory for the trades or opens it for a few seconds then closing it.
Whenever I restart the server the villager that has this problem changes.
the problem reoccurs to all the players of the server.
No mods / plugins are installed on the server
