An FUE surgery of 5,000 grafts is most likely too many grafts for the donor area in 98% of the population. As a result, you have a problem with over-harvesting which produces a see-through donor area. The original density may have been too low to support that number of FUE grafts you had done. You now have a depleted donor area, and since your hair appears short in the photo, this problem is made worse. If you let your hair grow out more, maybe it will cover this overharvested donor area. One reasonably good solution is Scalp Micropigmentation (see here: https://scalpmicropigmentation.com/scar-covering/).
Whatever you do, do not do another FUE as your situation will become worse. FUE is often promoted as a scar-less surgery, but clearly it is misleading as in your situation. You can either let your hair grow longer to cover it or get Scalp MicroPigmentation which will camouflage these bald areas exceptionally well.
