Bessel Equation VPASolve for the order

I am trying to solve a simple equation like
eqn1 = besselk(E,3)==5
for the variable E. But the problem I encounter is "Error using mupadengine/feval_internal. Unable to differentiate the equation."
Does anyone know an alternative way to solve this using vpasolve?

nu = 0:0.1:7;
B = besselk(nu,3)-5;
fun = @(nu)besselk(nu,3)-5;
nu = fzero(fun,[6 7])

I should have been more clear in my question, which I edited now. I was wondering if it was still possible to solve such an equation using vpasolve.
No. That's why I used fzero (or fsolve).
