Bug Animation Event is not always called (approx. called 95%)

Hi, I have an animation event which doesn't always get invoked.
Similar to https://forum.unity.com/threads/animation-event-not-triggering.456138/

I padded the end of the animation so that it was not the final frame (i know the final frame has issues being invoked) but the event is still not always invoked. The issue seems to occur more frequently when I run the application at a lower frame rate (30)

Event is started using .Play






I would like to fix this issue rather than change to timing things or using something like Animancer.
