However, switching the "Show indent guides" menu option off and then back on again brought the indent guides back (however, I know that trick doesn't work when I have 6-8 files opened in different tabs).

OK, this is weird.  I can't see any indented blocks when I open
subprocess.py without scrolling, so I'm presuming that at some point
you scroll to see that the indented blocks?  Also, what I most
recently did wasn't quite the same as you; I did the following:

* Open Spyder - the only tab is subprocess.py
* Scroll down a bit so I can see an indented block
* Wait about 20-30 seconds
* The indented block guides appear

Could you try that and let me know what you find?

Best wishes,
