Unable to export as uncompressed 16 bit TIFF from an Adobe RGB Canon RAW image on Windows 10
I've tested a sRGB Canon RAW and the export runs fine. But with an Adobe RGB Canon RAW file it simply mentions that it can't export. I've tried the same RAW on the 2.2.5 Linux version and it runs with no issue.
I've attached the RAW file.

I just tried on Windows 7 and your CR2 exported fine to uncompressed 16bit TIFF. It took quite long, but that's another bug. Do you have non-ASCII characters in your export filename or path? TIFF export doesn't support that.

I had the image on a folder which the name has some accents ("Pôr-do-sol"). I've tested the same export on a folder named "test" and it worked. So probably is that non-ASCII characters issue you mentioned.
What is odd, and as I mentioned previously, I tested the same image, on the same folder (with the same name, accents and all), on the 2.2.5 darktable Ubuntu version, and it worked. I'm using the Bash on Ubuntu on Windows feature that Windows 10 has, to also run darktable. I know that isn't supported but I had zero issues with it. Does the TIFF export module on the Linux version support non-ASCII characters?

I am surprised that you could open that file in the first place. LibTIFF has a bug where on Windows it's not supporting those filenames. There isn't much we can do about it.
