Hello, my project version 5.44 has a fatal error. I think the cause of this error is a defect in the version sequencer module. I used multiple sequencers in this project and referenced them in the player controller to start the runtime playback. There are generated enemy characters in the sequencer, and there are event tracks that control the parameters on the person characters. However, after I changed the blueprints on the enemy character, these sequencers and the blueprints referenced by them did not open and UE crashed when opened. I’m not sure if it was the sequencer, but when I removed the sequencer asset, the player controller BP, the map, and the enemy character BP turned on normally.
