Thanks Leo - indeed it was so suprising that I thought it was referring to the root of the chroot used to build rather than just the root of Ubuntu. This was a bad assumption on my behalf as /homeless-shelter really did exist at my filesystem root (containing a single .config directory with 2 yamls in it related to the python dask package). I moved the directory and everything is back to normal. Even stranger the datestamp on the homeless shelter was from November 2021, so why it decided to start fail yesterday I have no idea. Thanks again and sorry for the daft question - if I'd literally followed the advice in the error message I'd have resolved it myself! Way too much overthinking on my behalf!
