Error parsing extensions state: [Exception... "Component returned failure code: 0x80520012
I am getting an error "Error parsing extensions state: [Exception... "Component returned failure code: 0x80520012 ......." while the same was executing correctly earlier.
Please help me out to identify what is the cause of this error.

Where do you get this error? Do you use any antivirus software?
What project type do you run? Please provide the steps to reproduce.
So in my case i am using basic Selenium code:
System.setProperty("webdriver.gecko.driver","C:\\Users\\me\\Downloads\\geckodriver-v0.21.0-win64\\geckodriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette",true);
WebDriver driver = new FirefoxDriver();
Now when i run this in IntelliJ:

Unable to read VR Path Registry from C:\Users\me\AppData\Local\openvr\openvrpaths.vrpath
So the browser launches but then nothing happens. Firefox version: Version 56.0.1 (64-bit)
Could be caused by antivirus/firewall, as e.g. was assumed in similar geckodriver issue: https://github.com/mozilla/geckodriver/issues/952. Check with AV/Firewall disabled. Also try using different Firefox and geckodriver versions.
