I recently upgraded to build 1605 from 1573 and found I could no longer open fits files. This is on OSX Monterey.
The error I received is: "*** Error: Unknown or unsupported file type: /Users/schwim/tmp/dark_001.fits"
I did noticed that FITS-pxm.dylib doesn't appear to be loading in build 1605. FITS does not appear in the Format Explorer as well. I uninstalled and re-installed twice, including updating all modules and restarting, and was able to repeat. Rolling back to 1573 (folder backup) appears to get me going again.
I checked the release notes and didn't see anything about fits support being removed completely.
