found a solution to mine, i did the normal reset from “docker stop nextcloud-aio-mastercontainer” to “docker image prune -a” but it seems like it didn’t automatically delete the default NEXTCLOUD_DATADIR.
it seems like the /run/desktop/mnt/host/c/ncdata from the AIO Command & its hints tell us that there is a file at C:/ncdata which is left behind somehow. So i deleted that and started reinstalling, boom! its fixed.
