iCUE running on taskmanager, not opening

Today I updated my iCUE software, restarted my PC and then it just never opened again. It runs on the task manager, however I can't open it, and it's not on the system tray.

What corsair products I have:

• Corsair Void RGB
  
• K70 RGB
  

Things I've tried: (I've restarted my pc before and after every attempt)

• Restarting PC.
  
• repairing
  
• uninstall/reinstall (with and without keeping profiles)
  
• deleted %appdata% caches
  
• deleted config and tried to reopen after closing iCUE
  
• unplugging my devices
  
• uninstalling the drivers for keyboard and headset
  
• uninstalling the drivers for keyboard and headset then reinstalling
  
• Running as administrator
  

I've googled to try and fix this issue and those are all the things I have found. But after 3-4 hours none of these are working.

To mention, the software is using an abnormal amount of CPU usage after the install.

Ok, I went back to 3.18 and it works again. If anybody has this issue, go back.
