Dear James,
First, you will likely need to use .cub files as inputs rather than .tiff files which appear to be orthorectified versions of CTX data.
Your little video shows an error about a damaged libc++abi.dylib. I never saw this before.
I also wonder if you were able to prepare the needed .cub files with ISIS. For CTX, I believe that involves fetching .IMG files, doing mroctx2isis, then spiceinit. If you fetch ASP with conda, it will fetch ISIS as well, in the same environment, then you can
try to use the ISIS commands from that shared environment. Those will use the same libc++ as ASP's stereo command, and hopefully it will no longer say it is corrupted. Let us know.
