Winclone7 Error

Winclone 7.3.4 has run flawlessly on macOS Mojave so far. With update to 10.14.6 the following message appears after cloning progress of approx. 15%: “Cloning Error: There was an error while file imaging. Please check the volume and try again. Status:88”.
Do I need version Winclone 8? Download is no longer available. I don’t dare to update to Big Sur because the risk that Windows will no longer run is too high for me.

This sounds related to the filesystem. Try running chkdsk /b and reboot to the windows desktop, then try again.
