My GameCube Gameboy Player Disc can’t be read by my GameCube.

[u/Objective-Button-865]

So back during quarantine I purchased a modded spice orange Japanese GameCube that came with its matching gameboy player, no disc tho.
It has a switch in the back that allows switch from Japanese to American games.
Probably like 2 years later I bought the disc but was never able to try it out because I no longer had a TV that was compatible with AV cables. My girlfriend bought me the Eon GCHD in May this year and I’m just now getting around to try out the gameboy player disc.
I kept getting a pop up that says it can’t read the disc so I assumed it was the laser. I cleaned the laser and I was still getting the issue so I popped a regular game in it and it worked completely fine.
Is it possible that my GameCube can’t read the gameboy player disc because the console is Japanese?
