MATLAB: Error in syms: ‘The class ‘sym’ is used in its own class definition as a base class, property value, or attribute value. This is not allowed.’

solveSymbolic Math Toolboxsyms

My end goal is to solve a system equations for a variable. I have run into the problem that I cannot create any variables using syms. I have simplified my problem to the following for the purpose of understanding why i recieve the error below.
syms D
eqn1 = 4 == .002*D/1e-6;
vpasolve(eqn1, D, [0 0.01])
The following is what is returned in the command window:
The class 'sym' is used in its own class definition as a base class, property value, or
attribute value. This is not allowed.
Error in syms (line 227)
defined = sym(zeros(1, length(args)));
Error in Untitled (line 1)
