Siril 1.0.0-rc2 cannot open result.fit

I am using Siril 1.0.0-rc2 on MacOS 10.13.6. As a beginner stacking with scripts worked fine but Siril cannot open the final image result.fit because this type is unknown.It writes
The document “result.fit” could not be opened. SiriL cannot open files in the “Flexible Image Transport System document” format.
Can you please help.

Probably because the FITS is corrupted.
Lack of space disk?

Without sharing the file it is difficult to say though.

Thanks for your fast reply. There is sufficient space disk. Do you mean by corrupted that my raw files can be damaged somehow?

no. The file result.fit

I did it with the script OSC-Preprocessing-WithoutFlat which worked fine but all files in" Process" are marked “unknown”

As I said:

Sorry I can’t upload the file because it is too big. I will look for a cloud service tomorrow to make you share it. Thank you so far.

Somehow it doesn’t work with a cloud service as google drive, but I can open the file result.fit in Gimp.Do you think I should try it with a newer version of Siril as my laptop MacPro is almost 8 years old.
