Can't start activity in latest Sugar On a Stick Install (Sugar 0.113)

Hi - I installed SoaS and logged in. Once I click on the 'Moon' activity I am presented with this error:

Thanks. Interesting. The activity works fine for me on Debian and Ubuntu, but on Fedora 30 the same thing happens as you report.

Using Browse and opening /usr/share/sugar/activities/Moon.activity/index.html doesn't show the error.

The error complains of mistakes in the file. The index.html file does contain link and head tags, but there doesn't seem to be any mistake in assembly. Adding close tag markers at the end of the link tags does change the error message, but once I add all the close tag markers I get another error message; "This XML file does not appear to have any style information associated with it. The document tree is shown below.", and the index.html file is shown reformatted. I don't know why it has been interpreted as XML, given that it has a DOCTYPE html header.

Applying all Fedora updates doesn't fix it.
