D810 aperture error

Yesterday my D810 started displaying an aperture error when I went to use it, even with the lens set at f22 (aperture ring on lens) it was throwing up F-EE errors and rotating the ring through manual on Aperture priority would give me f22, f11 and f8 on an older 80-200 f2.8 ED Nikkor lens.
It was also showing aperture at f90 which has me very confused.
I've searched and searched, haven't tried doing the 2 button full reset as of yet after seeing people mention online it makes no difference.
I also tried it with a 24-105mm lens (Nikon) no change, an 85mm f1.4 Rokinon (non cpu) lens, an old 35-70 Nikkor lens (from my old F601) but not my 75-300 because I gave up and figured there's a problem somewhere.
I cleaned contacts on both camera and lenses with contact cleaner on camera lens cloth with no change.


The F-EE I'm familiar with if lens not locked at f22 (locking makes no difference as long as it's set at f22 it's fine) but the F90 confused me considerably, I've never seen that before



Is it time to send it to a Nikon service centre and if so, anyone recommended in NSW (sydney I'm guessing)?


Thanks!


Update:
It appears the camera works with a G lens, the problem is I only own one cheap, nasty G series lens and it's a DX lens (18-55mm).
I can manually rotate through various f stops and as long as I set the aperture on the screen to match where I move the aperture ring it seems to be continuous in luminance of the image but it constantly flashes between the chosen aperture and FEE.
I guess it's back to Nikon service because I can't find anything online.
With access to a strip down manual and I'd be prepared to have a go at it myself and while I can remove the camera mount ring (and did so last night out of frustration) I'm not prepared to go further without instruction, I don't want to destroy the camera, just get it working properly.


If it's of any use to anyone I did find a Nikon Z6III repair manual from Nikon themselves.
Not much help to me, I don't own a Z6.

After a lot of research (including watching a full disassembly video I found on yoo-doit (youtube) it seems there's a flexible circuit board behind the little aperture lever on the lens mount which must be damaged/worn.
I've contacted Nikon, they have suggested this may be the fault and suggested using AF-S lenses.
UHM, NO. I'd be replacing a 30 year collection of lenses from my old film camera days, some of which were very expensive when I worked and could afford such trinkets, off to Nikon repair centre in Sydney it is.
After watching the disassembly video I decided I could probably do the repair but exactly where I'd get the necessary part and how do I run yoo-idiot video in reverse to put it back together?

The white strip is an inductance magnetic stripe control unit, I love my D810 and am a little lost because its not functioning even if I rarely use it with poor health of late.

The part is quite cheap, likely non genuine but after watching the disassembly video I'm not prepared to effect the repair myself especially with migraine induced blurry eyesight most days. I'll leave it to Nikon and get the warranty me thinks.

Camera now at repair centre in Sydney awaiting quote.
The company I can't remember the name of sent me a shipping label so I didn't have to pay and even sent packing suggestions to protect the camera. I thought that was a very nice touch because some people have no idea how to safely package some sensitive items.
The free postage, there's a minimum $99 charge so effectively I am covering it but with their shipping label there's no chance of any postal/addressing errors on my behalf.
I hope it's not too expensive to fix!

UPDATE:
Camera has now been at repair centre for 5 weeks for over $500 worth of repairs (paid up front) for a $50 part. No camera for Christmas, no camera for New Years to shoot the local fireworks and no camera for my upcoming 65th birthday because APPARENTLY, Nikon haven't sent the parts.

I'm not happy and should have bought the part from Aliexpress for $30 and done the repair myself, NEVER AGAIN.........
