PC [HELP] Invalid platform error on Big Sur 11.1

[Doux]

I use Mac and recently got the new update, Big Sur 11.1. Its coming up with 'invalid platform' error, i have tried uninstalling it and reinstalling; updating steam; but the install button remains grey.

Is it just not available for Big Sur 11.1 right now?
