System Information
Siril 1.4.4 (official Windows installer)
Windows 10 Pro 22H2 (64-bit)
ZWO ASI585MC Pro
FITS images captured with APT
Official OSC_Preprocessing_WithoutDBF script downloaded using Scripts → Get Scripts
Problem
When running the official OSC_Preprocessing_WithoutDBF script, the script fails during the calibrate command.
The images convert successfully, but calibration immediately fails with:
Running command: calibrate
Checking sequences in the directory:
C:\Users\jpotc\Desktop\Siril WD\process
FITS error: failed to find or open the following file:
light_00001.fit
Could not load image 0 from sequence light_
Error in line 22 (‘calibrate’): invalid input sequence.
Script execution failed.
What I have tested
Deleted the process folder and let Siril recreate it.
Verified that all 150 FITS files convert successfully.
Verified that light_seq is created correctly.
Verified that light_00001.fit (the symlink created by Siril) opens correctly in ASIFitsView.
Enabled Windows Developer Mode.
Verified the original FITS files are valid.
Verified the working directory is correct.
The script being used is the current version downloaded through Scripts → Get Scripts.
Important finding
I uninstalled Siril 1.4.4 and installed Siril 1.4.1.
Using exactly the same:
FITS files
Working directory
Script
Windows installation
the preprocessing script completes successfully in 1.4.1.
The problem only occurs in 1.4.4.
This makes me suspect a regression introduced between 1.4.1 and 1.4.4.

I can provide:
Console log
One original FITS light frame
light_.seq file
Screenshots of the working directory and process folder
I have ruled out problems with the FITS files, working directory, symbolic links, and Windows configuration as far as I can determine.
Any advice or confirmation that this is a known regression would be appreciated.
