Cross-drive installation problem on Windows

I am trying to import a site on Windows. Local by Flywheel is installed on my C drive, a small SSD volume. (I was given no option to install it to an alternate location. Is there perhaps some hidden installer flag that lets me do this?)

I have changed the target directory for my imported site to my Z drive, as the C drive does not have the space for the install. Local by Flywheel hangs permanently at the “Extracting Import” stage. From log:
