ue5.6 plugin build

okey so i tried building RDR System | Fab from its source to use it with ue5.6 and after some minor changes to the code since pose search plugin had some minor api changes i built successfully and can open the project but the moment i open the map it crashes

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 1067]
Array index out of bounds: 0 into an array of size 0

CrashContext.runtime-xml (184.9 KB)
movement.log (134.1 KB)
UEMinidump.dmp (1.0 MB)

fixed it i can now launch the map but the motion matching isnt working everthing just slides with no animation and sometimes plays an animation for some seconds then stops
if anyone wants the built plugin to debug the problem just ask me and ill upload it here
