Here's what worked for me:
Unplug any corsair devices you're using. I had to use a different keyboard for this.
In the advanced troubleshooting options, open the command prompt.
In the command prompt, change your directory to wherever your OS/drivers would be installed. For me it was the c drive. (just type "c:" without quotes)
In the command prompt, type "dism /image:c:\ /get-drivers >drivers.txt". If you are not in your c drive, type whatever drive is applicable in "/image:[drive]"
Once that process is done, open drivers.txt simply by entering "drivers.txt" in the prompt. This will open the text file with the names of all your drivers.
Press ctrl+f and search for "corsair." Chances are, you'll find a few corsair drivers, including corsairvbusdriver.inf. Keep note of its published name, as it might vary for you. For me it was oem18.inf.
In
the command prompt, enter "dism /image:c:\ /remove-driver /driver:[publishedname].inf". I took this opportunity to uninstall all of the other corsair drivers on my PC, as well.
Close the command prompt, keep all corsair devices unplugged, and restart your PC.
From there, my PC was usable again.
