Install stuck in redirect loop / won’t recognise install

Using the latest duplicator version:

I’ve attempted a normal install at the following URL, however after successfully unzipping the contents of the archive, the install process seems to break and leave the site in a redirect loop:

https://lindoula.co.uk/w/

When I revisit the installer file I’m told to repeat step 1, though I have already done this and when using my ftp client I can see that the archive has successfully unzipped:

https://lindoula.co.uk/w/dup-installer/main.installer.php

Here is the output of dup-installer-bootlog__a4e8b95-30145035:
