OK I have finally success to test... the master version has a problem with opening pcsc readers on windows I revert back on older version to able to correct this problem. For the current patch without yubikey reference. I suggest validating the interference in the first task for the maybe_switch app function.

The patch on the patch for this is
removing the 1533-1534 1547-1548
add in 1501 this

/* This is for validation the external interference before to able to switch between app

if it is not possible to reselect the current app return bad card */
        if (check_external_interference (app, ctrl) != 0)
        {
            err = run_reselect( ctrl, card. card->app, card->app);
            if ( err )
                 return err;
         }

The result in the log
I have test the case 1 interference with gids and openpgp
Gids sign and Openpgp try to decrypt after.
Gids repport file not fount because the CA is not a get GIDS have CB for Get
