When I try to open a specific epub I get the following output from Sigil (yay cygwin

):
Code:
[3228:20216:1115/170205.254:ERROR:cache_util_win.cc(19)] Unable to move the cache: 5

Debug: LoadFolderStructure Issue: "OEBPS/Styles/page-template.xpgt" "OEBPS/Text/page-template.xpgt"
and just after that the following in a popup:
Code:
Error info: Cannot load file C:\Users\Simon\Calibre Library\Robert Penn\It's All About the Bike (158)\It's All About the Bike - Robert Penn.epub: OEBPS/Text/stylesheet.css
Sigil version: 0.9.991
Runtime Qt: 5.12.3
Compiled Qt: 5.12.3
System: Windows 10 (10.0)
Architecture: x86_64
If I manually remove the ...QtWebEngine\Default\GPUCache folder that removes most of the console output, but I still get the following two lines and the same popup.
Code:
Debug: LoadFolderStructure Issue: "OEBPS/Styles/stylesheet.css" "OEBPS/Text/stylesheet.css"
Debug: LoadFolderStructure Issue: "OEBPS/Styles/page-template.xpgt" "OEBPS/Text/page-template.xpgt"
Here's the output from "unzip -l" on the epub:
I can supply the CSS file (hoping no copyright issues for that), but guessing from the errors that the contents of the file might not be the issue?
This happens when opening via Calibire with the built in open-with, double clicking on the epub and starting Sigil from a cygwin shell.
According the modification time, I last edited this epub in 2011(!).
