Error creating file - unable to write ID tags/ unable to create file (Mac)

[QUOTE=neil74;184468]For use indoors I am absolutely sticking with FLAC. I am looking to convert for use on my phone (android device on Oreo wired use or bluetooth using LDAC)

Have a 128gb phone with no SD card so file size is a consideration[/QUOTE]

You'll be using earphones/headphones then. So, why the need for 320kbps aac?

BTW, I convert my flac files to mp3 (vbr, -V 1, approx. 220kbps) for use on an iPod Classic with Shure SE530PTH earphones. 220kpbs is more than adequate.
