Backup Problem

    When I try to use TLB's backup function I get a message saying backing up, with quite a few numbers and letters after. This disappears so quickly that I cannot copy it to the forum. Windows then crashes ( all the taskbar icons disappear momentarily and then reappear).

I have uninstalled and reinstalled but I still have the same problem.

I use Windows 10 Pro version 21H2 64 bit and TLB version 5.7.1 Beta

Edit: I have managed to get a screenshot of the message and attached it.
