See RAD Studio issue RSP-15872.
A workaround is given there (Dmitry Arefiev 18/10/2016):

This issue is major regression in Berlin 10.1 Update 1. The persistent fix will be included into Update 2 (time frame is not known at this moment). As a workaround at run-time please do the following:

    open Vcl.DBGrids.pas
    locate there TCustomDBGrid.CanEditShow method
    replace it code with:

    function TCustomDBGrid.CanEditShow: Boolean;


      Result := (LayoutLock = 0) and inherited CanEditShow;


add path to <RAD Studio run-time sources path>\Data\vclctrls to your IDE Delphi Library Path. It is the path where Vcl.DBGrids.pas is located. Is it ?
recompile your application.

I had to use wordpad to save the edited file but after this both TDBGrid and the decendent TjvDBGrid worked again.

Could you check if the issue is still present in the latest GIT content? If yes, please provide the zipped sources of an application showing this.
