+## [Unreleased]
+
+This patch release addresses a severe regression affecting UE `5.5` projects with specific settings.
+
+### Fixed
+
+- Resolved a critical deadlock between the rendering and game threads in Unreal Engine `5.5` that when `IHeadMountedDisplay::GetHMDMonitorInfo()` is invoked from `FSGXRTracker::GetControllerTransform()` in certain conditions; specifically while SenseCom is running and gloves are present and connected. This issue is [related to critical deadlock issue (UE-212224), occurring during PipelinedFrameState acquisition, which had already been addressed for the plugin versions running on UE `5.6+`](#260---2025-06-04). Because it only gets triggered under specific project settings, we were previously unaware that it also affected IHeadMountedDisplay::GetHMDMonitorInfo() in UE 5.5.
