Loading shaders on the Nintendo Switch used to work but aren't working anymore. Instead the game crashes when shaders are loaded. Shader files downloaded from servers appear as empty which could be the reason why the game crashes.
This has been reported twice before although it's been resolved as Invalid. This issue affects a large community of users who aren't modded. (Else you wouldn't be able to access online games because you'd be banned by Nintendo wink wink)

Sorry if I sounded rude but it's frustrating how the issue gets resolved as invalid without any attempts to recreate this issue.
