CD players use 780 nm light, which is infrared. What is transparent in visible light may be reflective in infrared.

How is that even supposed to work? The laser beam has to be reflected back down to the sensor in order to read the CD.

Plastics are typically transparent to IR

Translucent != transparent, but you might be on to something.
Maybe it works better on slim drives with a lower ceiling. Larger drives with space above the disc might allow the laser to refract and generate garbage.

I mean the CD does work. But not with all players… Not sure what makes some work and some not. Laser wavelength?

Most likely the sensitivity of the electronics and whether they consider the surely weak signal noise.
