InDesign 2023: Cannot place tagged text files <ANSI-MAC>

[Jordann28179401zngs]

I have been using tagged text for the past 14 years on brochures that I design. All the formatting is done for me when I export it the right way (from the client's system). I set it up this way... but fast forward to today: I cannot seem to place any tagged text. Did the coding change? I have used <ANSI-MAC> at the top of my text files and just place the text (then all my paragraph, character styles and grephs) work seamless. 

I place now and it doesnt read it. I've tried the way I hit return before and after that code, but nada changes. Still imports like this.

And if I tweak it too much it tells me "It cannot place this file. No Filter found for requested operation," I've reestarted InDesign, made sure everything is udpated and restarted my computer. Same result.
