Rsync trying to process a file that doesn't exist (due to internally corrupted filename or incorrect handling of NTFS file system?)

[HattonLe]

rsync version 3.2.7 protocol version 31, running on Ubuntu 22.04 LTS fully updated.
Backing up files from a source ext4 SSD drive to a destination NTFS formatted SSD.

rsync attempts to rename a file called ".aux.h.1mbKsI", however no such file exists in either the source or destination.
(The file in the source is called "aux.h", the other two files in the same folder are processed correctly and exist on the destination).

rsync: [receiver] rename "/media/main/SSD-480GB/BackupOfDocuments-12-06-2024/Src/linux-5.15.156/include/soc/arc/.aux.h.1mbKsI" -> "Src/linux-5.15.156/include/soc/arc/aux.h": Invalid argument (22)

Both file systems are fully valid and intact (the NTFS one scanned\verified by Win 10 as well).
