What is the bug or the crash?

Running QGIS 3.32.2 on OS X, installed in a mini-forge env with conda. QGIS does not appear to have projections from the IAU (International Astronomical Union) authority, such as IAU_2015:49910 (Mars, Sphere). These codes were added to proj in version 8.2.1 (or earlier) as per this bug report. When checking proj.db in the QGIS env, I can see that the code are present.

When searching for the IAU in QGIS, they are not present in the UI.

This was working in an earlier (pre-3.32.x) Conda-forge release. I do not know if this is a packaging issue, because QGIS should just be hitting the proj.db and pulling whatever is in there, without concern for the OS. To attempt to debug I looked in the QGIS preferences and see that the PROJ_DATA environment variable is being set. I tried also setting the PROJ_LIB environment variable, but no change. Interestingly, attempting to add the IAU code to QGIS throws an error that the code already exists.

Steps to reproduce the issue

1. Set the project CRS to an IAU_2015 code, such as IAU_2015:49910.
2. That code does not exist, even though it is in the proj.db (see screen shot above).
