AIO flashing red/Unknown device in ICUE

aio: corsair h150i elite capellix

So my computer was doing fine I've never had problems with the AIO before but while i was browsing i noticed my pump was flashing red, along with my ram, motherboard and rgb fans. I never knew they could all sync up but i tried restarting my computer with no fix and checking ICUE said "unknown device, pump failed"

I un and reinstalled ICUE and now the error doesn't even show up, but neither does the AIO. I found out that if i uninstalled it and installed the update before 4.33.138 that it would show the same error as before. If i unplug the top cable on the commander thingy then it stops flashing red but the pump doesn't light up at all, and of course still doesn't run. I've looked online and some other people have had this issue and maybe i did some steps wrong but even with the help in the comments i still can't get it to work. Right now the cpu isn't getting too hot around 20-25 but that's usual, so i can't tell if maybe the pump is still working or if the fans inside the case and on the radiator are just keeping it cool enough. Any help would be amazing!
