Try the fix in Exception: Cannot find PyQt5 plugin directories when using Pyinstaller despite PyQt5 not even being used. In short:
pip intall PyQt5
Note that, strangely enough, conda install PyQt5 may not fix the problem.
I encountered the same problem and saw another suggestion: make the missing directory (C:/qt5b/qt_1524647842210/_h_env/Library/plugins in your case) and copy the two files pyqt5.dll and pyqt5qmlplugin.dll (presumably somewhere in c:\Users[name]\AppData\Local\conda\conda\envs) to the directory.
I did not try it since I fixed the problem with pip install PyQt5. You may want to give it a try.
