You probably hit the file size limit of fat32
https://en.wikipedia.org/wiki/File_Allocation_Table
"The maximum possible size for a file on a FAT32 volume is 4 GiB"

Sadly there is no universal successor to FAT32 that is easily accessible
from all OS, so most external media is still fat32.

NTFS is quite good but doesn't ship with Mac by default
exFAT an attempt to bridge the gap requires work to be used on Linux or Mac
EXT2/3/4 requires drivers to work on windows
