Hello @Jojo Tang , I didn't see error code 0x80004005 in your snapshots. Could you confirm the error code? From snapshots, there is error code 0x80070005 when registering the sync root fails, 0x80070005 means "General access denied error" ( E_ACCESSDENIED in winerror.h). And I see "A3-???" in your sync path, so you can check if there is any special character in the folder name.
And for unregistering, the error from your snapshot is 0x80070057 which means "One or more arguments are invalid" and 0x80070490 which means "Element not found." If the sync root is not registered successfully, it seems expected you receive these two error codes when unregistering.
