Electra media player (with electra hap codec) in UE 5.4 working with hap worse than wmf player with hap codec plugin - bad seeking (really big delay), can’t open big files (UE 5.4, player freezes after this error):

After this error, I have to restart the Unreal editor to make the Electra media player work properly again.
