Members tab doesn't appear on group page and members operation link in group list doesn't work

Ok, just reimporting the group 3.x group_members view configuration (located in config/optional) fixed the problem for me.

Hello! what you report really happens :/. When Views detects changes to dependencies, it automatically disables the view.

To solve it, the view would have to be reactivated automatically (I have tried without success). In the worst case a message would have to be left indicating that the view must be enabled manually.
