Error 100123 - Many Threads, No fixes?

So I really want to like this program… as it is by far the most options with backup programs… but getting the 100123 error which seems to be many places on the forum and no solutions.

Windows 8.1
CB Ver 4.4.1
Using a Simple Copy backup

Backing up C: Drive NTSF to OneDrive (via Mapped Drive X:). Log is below. Wondering about the ampersand ‘&’ in the dir name or something else?
