Fix issue with app hanging after update to v0.6.0-2

Pull Request Description

This PR attempts to fix an issue with the latest nightly build hanging at the splash screen. I believe this is the cause of the issue but am not 100% sure, however, it could be due to a null check error when Material You theme is enabled.

I'll be creating a new nightly build off of this branch since there's been commits made already to the develop branch!

LGTM, although will the removals break the color scheme?

will the removals break the color scheme?

This should only affect users using Material You and a dark theme applied - I figured it'd be better to remove it now and make a proper fix for it once I push out a new nightly build!
