    Can you please post a Disk Manager image with the USB disk attached? Please expand the columns so we can read them.
    Expanded some more here.

    Disk Manager (C:\Windows\System32\diskmgmt.msc), not Device Manager.

    You have an unallocated partition on the Kingston.
    - Download https://www.partitionwizard.com/down.../pw11-free.exe
    - Install and run.
    - Right click on the Kingston D: partition and select Delete (it will delete the D: partition and all disk will be unallocated)
    - Right click on the unallocated partition and select Create. On the create window, select create as: Primary, format as: Fat32 and hit OK
    - On the top hit Apply to apply changes.

    You can also do the same with diskpart. Diskpart is a powerful tool and if you do something wrong you can delete your windows disk.
    Open a CMD window as Administrator and type:
    diskpart
    list disk (it will list all disks. Identify the kingston disk number)
    select disk x (replace x by the kingston disk number obtained on list disk)
    clean
    create part primary
    select part 1
    format fs=fat32 label="Kingston"
    exit (to exit diskpart)
    exit

    select part 1
    format fs=fat32 label="Kingston"
    exit (to exit diskpart)
    exit
    I followed the first step there, with one modification(I used NTFS instead of Fat32 when selecting the new primary, does it have to be Fat32?), but still get access denied on D drive when I have the USB drive inserted into my computer.

    Screenshot below shows how it looks inside diskmgmt.msc right now, and it says it doesn't have any error, so it should not be unallocated now.

    That is strange:
    - The USB flash disk is ok as you can access on another computer.
    - On your computer you can access all USB flash disk but the Kingston.

    Sorry, can't think anything else to do.

    try using imageUSB to "zero fill" the problematic usb drive (aka zero fill or zero usb is to do a full format of the usb stick)
    after the zero usb format, remove and re-insert usb drive and reformat in file explorer

    Try it as Fat32. The ntfs format supports ownership and security permission attributes which may be the cause of your problem, Fat32 doesn't.

    I tried that now and if I click on the D drive now, it says:
    "You are currently missing permission to use this folder. Click on continue to get permanent access to this folder".

    Then I click continue, then I get:
    "You have been denied access to this folder. If you want access to this folder, then you have to use the tab "Security"
