7. Only as you have moved to another window (the animation “shifting” the opening of a new window has worked), you can click on the Recent button. Now a recent search has appeared, when only the Claudia settings window was opened - there was no search line. In my case, there were three applications in the Recent menu, and you may also have to open something else in a manner similar to the one described above until the Google search bar appears in the Recent ones.

Addition from AleksandrOFF91 user:
After connecting Wi-fi, a line appears for writing a google account.
Choose a voice keyboard and say nothing. An error appears and an unnoticeable icon "planet" appears (voice input settings), select Google now, a window opens with information about this function. We refuse and get out the search string. There we have already entered the word settings and everything is like recovery and reset for all.
