play around with grip width. It might be that your grip is too narrow??? this makes it ‘more difficult’ to ‘keep the elbows up’ as your elbow isn’t in a stable position. It will also allow you to get full lateral rotation of the shoulder and keep the wrist in a comfortable position (by the way – how is your wrist / finger mobility?)
Once in this position it’s actually difficult to ‘drop’ the elbows performing a front rack squat.
