Boolean in animgraph transition cause crash

Hello there all, I have a weird issue, where a simple boolean condition is causing my system to crash
and it provides to following

"Assertion failed: IsRotationNormalized() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Math\TransformVectorized.h] [Line: 472] "

According to chatgpt it means that my transform Ik rig values are not normalized.

I want my leg to go up when the user is holding RMB as a condition, so when the user is holding RMB the bool is set to true,this is the blueprint.

and in the animgraph state machine between the idle and the leg lifting the condition is obviously the bool, is holding RMB
if it executes well then a logic is being set for a variable - “leg lift” and this variable is fed to an ik rig node location pin.

This only happens with an ik rig and a boolean and a hold/ hold and released/ trigger ongoing pin

I did try to use an event tick and to set the variables with a dynamic get socket location, so that it will receive each second a value thus normalizing them rather then no value at all.

I wired an animation pose to the IK rig node, which ended up solving the crash.
since the ik rig doesn know where to start from (0,0,0) it crashes when applied values.
so an animation pose seemed to solve it

Can I ask why you are setting the bool value every frame with the “ongoing” execution pin? And then clearing the bool every frame with the tick execution?

If you want the bool to be true when the button is held why not just set it with the “started” pin and clear it with the “released” pin?

forgive me for the lack of knowledge, but doesnt “ongoing means holding an input”
started is just one time as far as i know
