I’ve found myself in a similar, although, waaay less bad situation. Imho there are basically three ways:

1. Embrace the stupidity, do the bare minimum to stay employed, try to game the reviews, find meaning in your private life, side projects and hobbies

2. Enjoy that you get paid for drinking coffee while it lasts, and spend the time you have writing applications and acquiring stuff that looks good on a CV

3. Quit, whether on your own or by literally doing jack shit, accept the unemployment and/or worse job you might have to take. May or may not be an option, depending on the situation.
