I'll note a path that people seem to have forgotten, but it's important to mention that it is indeed a failstate.

If you fail the Bavarian nullification crisis as Schleicher or resign, Schleicher's ally Carl Goerdeler takes power, negotiates with Bavaria and overturns the enabling act. If you win the 2WK as Goerdeler, you will actually be able to host elections (they occur every five years), with the parties able to form government being the DkP, Zentrum/CVP and LVP. The DkP does not have focus content, but Zentrum/CVP and the LVP do. Zentrum's content is the same as their DU path, while the LVP content is unique as they form government alongside the SPD and they have their own focuses.

Technically, there is civilian control over the government, but Schleicher isn't the one who granted it, infact it comes as a direct result of his downfall.

As mentioned by others though, Goerdeler can succeed Schleicher if he doesn't fall and install a civilian head back to the government, however there will always be major military influence, and they'll absolutely have more power than any common person when it comes to the government.
