QWERTZ is used in Germany, Austria and much of Central Europe. Its signature is the swapped Y and Z, chosen because Z is far more common than Y in German. The umlauts Ü Ö Ä take the three keys to the right of P and L, ß sits on the number row where QWERTY has the minus, and the number row’s shifted symbols follow the German order (" § $ % & / ( ) =). Physically it is an ISO board: two-row Enter, # beside it, and the < > | key next to the left Shift.
Press every key across all five rows. Pay attention to the three umlaut keys and to # and <, which only exist on ISO boards. The right Alt is Alt Gr: hold it with Q, E or the digits 7–0 to reach @ € { [ ] }. Each keycap shows how many times it registered, so a key that never lights is dead and one that jumps by two is bouncing.
That is a layout setting, not a hardware fault. Windows or macOS is currently using a US or UK layout with your German keyboard. This tester still highlights the physical key correctly, because detection ignores the character; switch the system layout to German (QWERTZ) and the letters will line up again.
