Im trying to replicate a locomotion system like lyra’s locomotion.using blueprint thread safe override and calculation variables within tread safe like locomotion angle and direction with property access node.Also using orientation warping.
It worked perfectly for a few hours then it started to crash when i try to move nodes which includes calculation datas from thread safe and property access.
First i suspected it was something with the animation warping plugin, i tried creating all setup in fresh project and swapped between different engine versions, not fixed.
Its probably something about ThreadSafeOverrdie and PropertyAccess node.Any ideas?
Here is the crash log;

//UPDATE
So good news is i fixed it.Here what i tried;
Been thinking it was about the animation warping plugin and ThreadSafeOverride and PropertyAccess node, seemed llike it also happened when i click LegIK node which is a skeletal modifier node.
A fresh project with same setup didnt work.
-Different engine versions, didnt work.
-Updated, graphic driver, VisualC, Directx none worked.
-Tried Lyra sample as soon as i clicked OrientationWarping node it also crashed.
-Compeletyl deleted Epic and all engine versions including CDrive/Users/Appdata folders.After a clean installation it worked well but suddenly crashes started.
The issue was something related with AnimBP viewports.I was disabling when i working on BP editor then it was crashing.So i opened at least one viewport in AnimBP and the crashes suddenly gone.So weird.
Topic can be marked as SOLVED.
