fix: error message should not be localized in the player class

[gjanblaszczyk]

Description

The "not supported message" should not be localized in the player class because an "Error Display" class localizes all error messages before showing them to the user.

Nice catch, thanks @gjanblaszczyk!

I don't know what codecov is complaining about here, but this is fine.
