Maybe you stumbled upon a bug, lucky you. :-)
The commands look right to me. I have an external disk that I can try to toggle types and see if it does as you are seeing.
The only thing that I could guess was that your partition table is in a read only condition by a feature in bios, caused by some AV progam you had on the disk prior. Your partition table might be corrupted and fdisk gives you the invalid argument, error 22 response.
I haven't toggled from fat32 to Linux recently. I did toggle to lvm and it seemed to take. It was a type 83.
