Siril (2 versions) for Catalina could not load sequence

I loaded 32 image files and converted them.
I even loaded only the converted fits files, and it gave the same error.
The log (attached here) showed the error “Could not load sequence”.
Is there a problem with the loaded file format?
I cannot see where the problem is.

First you use a too old version I see.

Then you have many issues. You try to debayer a 3 channel image. It is not possible.
Then, remove all seq files to be sure there is an issue.
