Presumably you've been using ntfs-3g previously, not the old in-kernel NTFS module (which is rather unmaintained and supports only very basic write access; kernel >=5.15 will ship with the new ntfs3 driver developed by Paragon Software).
Yes I used ntfs-3g in 19.07. Correct me if I am wrong but ntfs-3g does not contain anything that allows the Mounting of the drive. I tried using just block-mount and ntfs-3g and could not mount the drive.
Did you format the drive by chance? The 2tb limit refers to partition size rather than drive size, so if you had multiple partitions less than 2tb before and reformatted to one partition of 5tb that would explain the error.
