Hello! I’m trying to open some DICOM files with ParaView 5.6.3 (also with ParaView 5.7) and I’m getting this error

```auto

I saw a similar question in this forum and it was related with a typo, but I usually have no trouble opening this kind of files with this naming. Anyone knows what could cause this?

Thanks!
