what version of selenium are you using?

looks like it was resolved in #7390 for alpha-version, but stable is still suffering from this

error
' Message:
System.IO.FileNotFoundException : Could not load file or assembly
'WebDriver, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'. The
system cannot find the file specified.
Stack Trace:
PageObject.ctor()

I guess it connected with SeleniumExtras.PageObjects
