Two users. Apparently partition 5 was setup to be accessible only to user chris. If you check with ls -l/n you'll likely see only user 1000/chris and group 1000/chris has permissions enabled.
There are various ways to fix this; a sampling:
Adding chrisontde to group 1000/chris plus adding group write permission to /media/chris/DATA could be a start. I wouldn't do it quite that way. One way I might start would be by adding a fstab entry for partition 5 to mount it in /home/DATA to make it easier to get to. /media/ is intended for use of removable media, so not an ideal location for your nvme's partition 5. And it wouldn't be a full solution without knowing whether having two users is what you really want. If you really would rather have only one user, then I'd add a basic fstab entry, followed by giving that directory rwx permissions to your sole user. If you really want two separate users, I'd also symlink /home/DATA to both /home/chris and to /home/chrisontde, besides enabling both users full access via some shared group.
