CRITICAL BUG: Build update deadlocks Strategy Tester – Reinstalls fail, major exploit/stability issue

[littlegrim]

The latest MetaTrader 5 terminal update has completely broken the Strategy Tester environment. At the very end of a backtest run, the terminal encounters a severe thread deadlock/memory leak, forcing the platform window into a frozen "(Not Responding)" state.

This occurs on a completely clean, localized local drive environment with zero cloud synchronization active. A fresh uninstallation and clean reinstall does NOT fix the problem. Even attempting to roll back to an older version fails because the terminal immediately forces a background live update back to the broken build. The only way to exit the platform is a forced crash via Windows Task Manager.

MetaQuotes, you are actively jeopardizing 25 years of platform greatness. Pushing untested updates that completely halt automated strategy validation is a costly mistake that will cause you to lose millions in marketplace profits as developers migrate elsewhere.

This bug completely halts automated strategy deployment for the rental market. We need a stable, archived terminal build rollout or an immediate hotfix patch to resolve this tester freeze now
