How to resolve Offline Files Sync Schedule Error (Access is denied)?

After a recent Windows 10 update, the sync schedule for my offline files is no longer accessible. The offline files pairing works properly -- that is, in Sync Center pressing Sync works without error. But pressing Schedule results in a message box:

[Window Title]
Sync Schedule Error

[Content]
An error occurred displaying sync schedules.
Error: 0x80070005
Access is denied.

Does anyone have a resolution for this?

Update: After installing the Fall Creators Update, a new message appears (though it might be different because I screwed around with something somewhere on the system trying to get it to work):

[Window Title]
Sync Schedule Error

[Content]
An error occurred displaying sync schedules.
Error: 0x800700b7
Cannot create a file when that file already exists.
