I'm wondering if changing the stem from a 120mm to 100mm or even 90 might fix this issue I'm having?
That's quite reasonable.

Most likely.
Most fit starts with KOM mentality (right or wrong), it's a relationship between saddle and knees. The idea is to get that correct so you don't have orthopedic issues. Then you adjust reach separately and independently of that, such as with stem length, flipped or not, bar reach, bar drop, spacer stack.
