MBAE and MBAR, Access Denied, visible TMP files

[slack7639 0]

Using Win 10, MBAE and MBAR

I was unable to rename folders, and move files from one folder to another.
I did a Restart, and was able to, but then this would start again.
I turned off MBAE - no effect . . . I turned of MBAR - back to normal.

I'm working on an xlsx, and save it . . . What are these Temp files I see in File Explorer?
I turn off MBAE . . . F5 to refresh the folder . . . they disappear
I type something else into the xlsx, save it, and get the Temp files back
I then turn off MBAR . . . no F5 required, they disappear on their own

I haven't noticed this issue recently.  Did it get fixed?
