aRGB Header not communicating

[RuleLessWonder]

I built this PC at the start of 2021. Using the included fan controller from the AIO plugged into my aRGB header I was able to control all LEDS from Polychrome (case, AIO, mobo, RAM). However, I didn't have a graphics card yet and was running Intel graphics. I noticed after installing my new graphics card that my RAM had reverted to rainbow. When I tried to use Polychrome, it didn't detect the RAM or Graphics card (options grayed out) and the aRGB header was not responding (acted like all was fine, but nothing changed in LEDs). I tried the select all option and the only LEDs Polychrome was able to grab were those directly on the mobo PCB. I was able to install Dragon Center to work with the graphics card and G Skill's program was able to detect the RAM, but the only was my AIO is currently able to be controlled is via the remote that came with my case controller. I've tried uninstalling all RGB controller software and reinstalling only Polychrome to no success. I've tried changing to another RGB header on my mobo. Nothing seems to be able to communicate to or detect the fan controller plugged into either aRGB header. I'm starting to wonder if my cable connecting the fan controller to the aRGB header is faulty?  Any troubleshooting tips or insight much appreciated!
