This seems to have been fixed at some point. With SymbolicUtils 3.7:

julia> using SymbolicUtils
julia> @syms p r s q
(p, r, s, q)

julia> 0.5 * inv(-0.5 * inv(p) ^ 1 * q * r + p + s) ^ 1 * inv(p) ^ 1 * r ^ 2 * q + r + -1 * (0.5 * inv(-0.5 * inv(p) ^ 1 * q * r + p + s) ^ 1 * inv(p) ^ 1 * r ^ 2 * q + r)
