NoXPlayer 3.31.11

Fixes a self-inflicted white-screen regression

3.31.2's fix for the stuck catalog-sync-prompt buttons introduced its own new bug: a solid white screen for several real seconds on every cold launch, caused by the app's very first frame referencing service objects that hadn't been created yet. The splash screen (meant to show while caches/catalog load in the background, so the main app feels instantly ready once it opens) now reliably shows for that whole window again instead of intermittently crashing white.

This is separate from 3.31.9's native-launch-screen fix — both white-screen causes are now fixed.
