That depends on the setup you have. Each GPIO can only be used once. E.g. if you use a DAC, that may be using some of the GPIOS, which then can no longer be used for the rotaries.
Due to the enormous amount of possibilities, it is very difficult to say from a distance, what your particular problem may be.
The section with „debugging instructions“ gives some hints how to collect information we need to support you.
There is also some more info about how to generate and share logs here.
