Market replay closes

Platform: NinjaTrader 8.1.6.3 (64-bit)
OS: Windows 11

I am experiencing intermittent crashes only when using Market Replay.
NinjaTrader works normally for live trading and simulation, but closes unexpectedly during Market Replay.

Event Viewer shows:

  • .NET Runtime internal error (80131506)
  • KERNELBASE.dll
  • System.AccessViolationException

The issue occurs even with the Custom folder disabled.
Visual C++ Redistributables and .NET Framework were repaired.
Drivers are up to date.

This only happens on one Windows 11 machine.
Please advise if there is a newer build, hotfix, or known issue regarding Market Replay stability on Windows 11.

Recommend you contact NinjaTrader support directly.
