Parts of Siril freeze in Win11

I am not able to get the Photometric Color Calibration to work in Win11. The error message comes up "Could not load the the star catalogue (generic error). The four catalogues have been download and uncompressed. The problem is that the Astrometry window is not working in Win11. The location of the local star catalogues is identified but the Apply button is non-functional. I click on that button and nothing happens.

There is a log file for Siril but it was not accepted for upload.

Hi,

Apply button is just updating the config.ini file located in %LOCALAPPDATA%\siril folder, so nothing special is expected to happen when you press it.
Now the error is strange. Just tested myself with 1.2.6 and local catalogues, and it solves and performs the color calibration alright. Can you share your image? Can you also copy your config.ini file?

Cheers,

Cecile
