Octane Blender Addon constant freezes/crashes

Problem: Constant IPR switches during editing process may cause Blender and Octane Server to freeze (Application Hang). What is actually happening: Octane server may freeze when I try to start IPR, which also causes Blender to freeze, as IPR does not start and there's no "feedback" from the server. Octane server can't be terminated as usual (right-click) and can be terminated only with the task manager.
Sometimes it just say "Finalrender or other Rendered viewport is active" without any freezes, but both Blender and Octane Server need to be terminated via the task manager.
It occurs randomly regardless of the scene, ranging from an empty scene with a cube to complex projects. Nothing similar happens with a custom build.
Blender debug logs included, but they say nothing useful. Octane logs may indicate the culprit on NT_RENDERTARGET state change.
Specs:
[Blender 4.5.5 LTS]
[OctaneServerStudio 31.0 BETA]
[NVIDIA Studio driver 581.57]
[RTX 5080 + RTX 3080 Ti]
