You likely have an incompatibility in your environment. Can you specify how you created the environment, perhaps run conda list to show the versions of all the packages you have? Note that with the standard Anaconda installer, spyder lives in your base environment, so you should always run it from the base env, and there should be no need to try to install it in any other env.
