Application spyder launch may have produced errors

Question

I am trying to launch Spyder from Anaconda and keep getting the error copied below. I tried updating python.app, installing Python 3.6.5 and other suggested solutions but had no luck.

Any suggestions?

I'm trying to launch spyder 3.2.4 on macOS Mojave 10.14.2.
