Yikes. Did that all start at once or have these kinds of warnings increased over time?
The one that jumps out to me most is that AIGrid::ProcessFloodHeap. Sounds like a memory exhaustion issue if the term is being used in typical software jargon.
"Trying to RegisterForgetEffect nullptr effect" is also pretty bad sounding.
Don't even know where to begin really with all those warnings. Sounds like something fundamentally broken, corrupted, or pushing this tool beyond its limits.
