Why is G chord so difficult?

I've been trying to learn to play a guitar for two weeks now, I can already play several chords, but not the G major chord. I feel like my pinky just doesn't work properly💀 When I place my second finger and third finger on the fretboard, there's no problem. But as soon as I add my pinky everything gets so bad. I can't fret the strings properly, and the sound is not clear at all. Did anyone else have this issue? Cause at this point I'm almost convinced there's something anatomically wrong with my pinky💀
