Probably because both apps, the Configuration Editor and Device Selector, crash due to an audio device of which these apps can retrieve the specs. This usually happens when some remainders are left of a deleted audio device. Unfortunately this is difficult to establish and to solve. You might run a registry cleaner like Wise Registry Cleaner or the registry cleaner of CCleaner. Hopefully that solves it although not guaranteed.
