Summary
Mobile Preview (This PC) crashes Fortnite immediately on launch, making it impossible to test mobile-specific gameplay, UI, or input issues. Due to Fortnite Mobile being unavailable in the UK, this completely blocks my ability to debug or fix reported mobile-only issues affecting live players.
