New to gimp, having trouble importing images

[PixLab]

So today I did try on a Mac with Catalina, and I can comfirm that it might be a corrupted file, because drag and drop directly from Finder, works as it should, and I don't think it's a right problem because I did also try with a DMG that I did not install but opened from the virtual drive and same it works as it should (I did learn something, though, it reset your preferences on the installed GIMP when you open from the virtual drive)
