Windows 10 Client Sync Issues - Access denied during file rename

Running up a Nextcloud instance for the family on my homelab on my esxi server.
Installed the Vmware version of the server a couple of days ago and got that going. Created a couple of users. All good.

Installed the Windows desktop client on my notebook, ipad and iphone, all good.
Installed the Windows desktop client 3.1.2 on my desktop and it’s giving issues with most of the files.

Excerpt from the local log file:-

It doesn’t appear to be a NTFS permissions issue, I tried :-

  • Giving my user (who is an admin) full access to the sub-tree.
  • I tried running the client as admin.
  • I gave EVERYONE modify access to the sub-tree.

My desktop is Windows 10 20H2, all the latest patches (same as my notebook)

This isn’t every file from the initial sync, about 90% of them, I’ve only got about 300meg in total, the largest file is about 100meg.

I don’t know where else to look, it should work ???
