Ok tried 3.6.8 and 3.6.9 09 fec 2024 build and both work.
Now I try the 3.6.9 01 Feb release it now works.
Looking at the .xml profile 'ZWO CCD ASI294MC Pro_config.xml' I see it is now much bigger and has been re-ordered.
I suspect the old one was somehow incompatible with the new version.
When I ran 3.6.8 or 3.6.9-09 Feb it saved a new version on exit.
Just guessing.
