Sequence does not play!!!

i think i have a similar problem in 4.26. maybe what i have found can help a bit to get this solved.

i have a app where i read/write and control sequences. therefor i have a blank LevelSequence in my content folder. at startup i call ULevelSequencePlayer::CreateLevelSequencePlayer to create a SequenceActor and Player. on windows this works fine but on android there are two things happening that completely f**k up my app.

  1. the SequenceAsset is null. it is set via property like this
    UPROPERTY(EditAnywhere, BlueprintReadOnly)
    ULevelSequence* SequenceAsset = nullptr; //set to a certain asset in editor

  2. the ULevelSequencePlayer::CreateLevelSequencePlayer throws an exeption “SIGTRAP: trace trap” and never gets created correctly

■■■ a result i can not control the sequence.

so that makes me think is there anything wrong with the sequence playing tools on android?
