My apologies. I was rushing to get my question posted and I'm afraid I was sloppy.
The error is occurring with MariaDB 10.4.8 x64 and the directory is ./tmp/MariaDB/
That clarified, I have checked the permissions on multiple occasions and all I can say is that if I right click on each of the directories, choose properties then the security tab... authenticated users, SYSTEM, administrators, and users, all have full permission.
Per MDEV-30162 this might be AV or some other process taking a look at the MariaDB temporary file without leaving MariaDB the permissions to delete it.
