Try:

  p[q_] := q^-\[Delta];
  Solve[q + (p[q] - \[Tau])/p'[q] == 0, q]

  (*{{q -> 0}, {q -> (-((-1 + \[Delta])/\[Tau]))^(1/\[Delta])}}*)

Solved on Mathematica 13.2.0.

Thanks for the reply; same error message here. I'm absolutely clueless why that is.

This is a warnings message not errors .

Is about:

1.This message is generated when Solve and related functions use inverse functions to represent a solution.

2.Inverse functions normally give one branch of a general inverse, so equations that are solved in terms of inverse functions may omit solutions associated with other branches.
