Teracopy 3.12 problem faile name.

System: Windows 11 22H2 22621.2428
Teracopy: 3.12

I am not a native speaker, I use deepl.

Teracopy has a strange problem with the names of certain files. It happens from time to time that when copying/moving files, some names are not taken but an alphanumeric abbreviation remains as opposed to the system using windows 11.

Teracopy is useful to me because it preserves the chronological data of files as opposed to the windows file copy.
Why does this happen ONLY for certain files?
