Can't copy to external NTFS hard-drive since Sonoma upgrade

I have a 4TB NTFS external hard drive that I copy to quite regularly however, since upgrading to Sonoma I am unable to write to external media, not just my external hard drive but also memory sticks. Is this an issue with the upgrade itself?

I do have a workaround; however, this is not a satisfactory solution. My M1 MBA sits on a network with a R-Pi server, two Windows laptops and an old Black-Mac. I can plus my external drive into any of these machines, create an SMB share and Sonoma has no problem writing to a SMB share. As I said, it is a workaround but not satisfactory.

NTFS is a Windows only format. macOS cannot natively write to it and requires a 3rd party driver to do so.

If you had an NTFS driver such as Paragon or Tuxera, macOS updates general break these drivers. You will need to get an update from its developer for Sonoma to make it work again.

macOS can NOT natively write to an NTFS volume. You will need 3rd party drivers/software to do that.
