Games dont launch from game menu

For some reason on my rg35xxsp the games wont launch through the frontend, and actually even freeze it. Weird thing is if i go to tools/retroarch and manually load the roms from there, it just works, so i dont understand what’s broken on the frontend’s scripts. This is the log i rescued from retroarch, which seems to be passed the name of the core and not the filepath:

[WARN] --libretro argument “/mnt/mmc/MUOS/core/FCEUmm” is not a file, core name or directory. Ignoring.
[INFO] RetroArch 1.20.0 (Git 919868aa0a)

I should specify i migrated all to sd2 and my roms are also on sd2
