Hello, I’m trying to change the anim class when anim montage has finished, but I’m getting assertion failed for !bPostEvaluatingAnimation and PostAnimEvaluation already in progress, recursion detected for SkeletalMeshComponent .

if (animInstance && MontageToPlay) animInstance->Montage_Play(MontageToPlay, 1.f);
FOnMontageEnded onMontageEnded;
onMontageEnded.BindLambda([this](UAnimMontage* montage, bool bInterrupted) { GetMesh()->SetAnimInstanceClass(NewAnimClass); });
animInstance->Montage_SetEndDelegate(onMontageEnded);

Am I missing something before

GetMesh()->SetAnimInstanceClass(NewAnimClass);

?
