Fatal Python error when running profiler in macOS app with external environment

[mrclary]

Description

What steps will reproduce the problem?

Attempting to run the profiler on a simple test script in the macOS app results in the following error:

That PR can't be merged for Spyder 5 because it's a significant change to the way the Profiler works.
