FC Mobile Black screen error

FC Mobile frequently has a black-screen bug on my Redmi 7A. It can happen when starting a match, opening packs, events, or ranking up players. Sometimes the game automatically closes when starting a match or performing an action. During the black screen, commentary, crowd, and button sounds may still continue. Strangely, the game sometimes becomes normal again for a few days, then the issue returns. Please investigate and fix this recurring problem.
