Hi Amie,
Glad you got it working with PyQt 5.10.  Do let us know if you run into any more problems.

I tried the code you wrote and also edited it based on the link you sent and neither way worked. I ended up with the spyder version distributed by anaconda and a separate version of spyder. They didn't play well together it seems as the individual version wouldn't open (it just froze).

To get around this, I went into the mne python environment file, changed the PyQt5 version to be ==5.10 (rather than >=5.10), and reinstalled mne python. This has worked! Now spyder opens from within anaconda.

Then, when you launch Spyder, change the "Preferences > Python Interpreter > Use the following interpreter" setting to match the python executable in the MNE-Python conda environment. This would look something like:
