[RESOLVED] Multidisk won't start in duckstation

I am trying to play a PSX game on retrobat 5.2.0 on windows 10
When I launch the multidisk .m3u in duckstation, the game does not start and goes back to emulationstation
Single disk .cue and .iso start fine.
If I start duckstation without retrobat and load the .m3u file, the game starts without problems.

Why doesn't the game start from retrobat?
Is there some setting I need to do?

"Hi" (not optional here)

I have tried with m3u and Duckstation on Retrobat and it work fine.

Thank you!
I did my best to check it out!
The character encoding of the .m3u file was "UTF-8 (with BOM)".
I changed it to normal "UTF-8" and it works!
