This resolved the issue for me!
I was dynamically creating attribute sets for actors. So, for those actors who didn’t have the relevant attribute set, the ability that committed the cost of that attribute crashed the game when activated!
Example - Jump committing stamina cost on an actor that didn’t have stamina attribute set.
Hope Epic fixes this. Commit Ability is broken. This is the second time commit is causing a crash for me - the other time when Super::ActivateAbility(...) incorrectly Commits ability (Fixed in UE 5.3).
