• Crashes with logs screaming "Failed to load chunk" or "Map data corruption"

This hits both single-player worlds and servers, especially custom maps or modded packs. Recent spikes in reports tie to 1.21 Tricky Trials update, where new trial chambers overload weak hardware. But fear not – 90% of cases are fixable in under 10 minutes! 🔧
