David it looks like mathics pins the SymPy version. You probably have an older version since on GitHub they are asking for sympy==1.4: https://github.com/mathics/Mathics/blob/1927ada93c5ce2d8cbe731731ab1f55cd5527467/setup.py#L66
I guess that they will update that soon but in the mean time you will have to use separate environments so you can have mathics in one and SymPy 1.5 in another.
