This appears to be issue related to the one here: https://stackoverflow.com/questions/36003023/json-dump-failing-with-must-be-unicode-not-str-typeerror/36003774, and probably caused because this Win10 version is the last with py2.7 integrated.
I haven't run into this error myself, so I'm not sure why it's happening for you. I see three options for you: 1- Figure out what unicode characters were being used that caused python to want to save it as unicode and don't use those (possible temp workaround) 2- Modify cache.py manually using the information on the SO link so it's compatible. 3- Wait until I release a Python 3 version of GR 3.8 for Win10. This is the next task in my list, but I make no promises as to timelines. In the meantime, you could try 3.8.0 or 3.7.x versions.
