Unable to find explicit solution

Matlab says "Unable to find explicit solution" when trying to solve following non linear equation
-log(y) = psi(1/2+ x/y) - psi(1/2)
Here psi is digamma function
What is wrong with my code, below?
I am using matlab version R2021a
syms x y
eqn = psi(1/2 + x/y)- psi(1/2)+ log(y)==0;
soly = solve(eqn,y)
Warning:
Unable to find explicit solution. For options, see help.
> In sym/solve (line 317)
soly =
Empty sym: 0-by-1

It seems very plausible to me that an explicit solution does not exist. Do you have reason to think otherwise?
