Taillight Hyperflash Issue

I have a 2016 Tacoma SR5, I have after market headlights and tail lights installed. I do have the LED Load Resistors instilled on my taillights so my blinkers work properly. The past two years I've had absolutely no issues with the blinkers or any of the lights, recently my blinkers stopped working.
When non of my lights are on the blinkers don't work at all but when i have the lights on they Hyperblink. I thought maybe the LED Load resistors went bad so i replaced those and still no change so i checked all my fuses and bulbs and still no issues, I took my truck to the shop and they cant figure out the issue either.
I'm very lost and cant seem to figure out a solution to fix this issue, any sort of help would be greatly appreciated.

 

Do you still have the oem taillights laying around?

 

Yes I do

Yeah you have a load problem. Try removing one of the led resistors doesn’t matter which side see what happens, also check grounds and the individual bulbs make sure none of the individual leds are burned out.

 

The failing part is pointing to the Combination Meter since the flashing relay is an integral part of it, not a separate flasher like the 2nd Gen.
