The error is, that my glasses do not have the resolution to parse your screen shot. At least the message looks more orange than red, so it is a warning, not an error.

Documentation of 'dsolve' goes through this warning state and explains what measures can be adopted when this warning is returned.
In summary, If dsolve can find neither an explicit nor an implicit solution, then it issues a warning and returns the empty sym. Returning the empty symbolic object however, does not prove that there are no solutions.
In this case, try to find a numeric solution using the MATLAB® ode23 or ode45 function. In some cases, the output is an equivalent lower-order differential equation or an integral.
Hope this helps!
