I told you this would be fun. I'm using the Guest folder as a test case and none of these have worked. :-)
I am no Linux geek but I did find https://linuxize.com/post/chmod-command-in-linux/
I searched on the commands gave me and got that same result!
;-)
I typed both suggestions and combined into a question when I searched https://phoenixnap.com/kb/create-directory-linux-mkdir-command
I didn't have to search, I use these commands a lot after uploading files over SFTP. ;)
ls -la /Path/To/Users
'/Path/To/Users' only, not '/Path/To/Users/[USERNAME]'.
Copy and paste the result here.
Slightly modified to protect the guity:
$ ls -la Users total 0 drwxr-xr-x 1 root 80 6 Mar 8 2014 . drwxr-xr-x 1 root root 38 Sep 26 2014 .. drwxr-xr-x 1 501 dialout 21 Mar 14 2015 foldername drwxr-xr-x 1 201 201 11 Mar 8 2014 Guest -rw-r--r-- 1 root root 0 Aug 25 2013 .localized drwxrwxrwt 1 root root 11 Dec 5 2015 Shared

You have to change the user:group with chown as mentioned in my first comment.
sudo chown root:wheel -R Guest
