I don’t see anything really obvious wrong with your blueprint so here’s some troubleshooting things I would check or possibly maybe you will get an idea of what to look for that could be causing the problem.
Is it possible that your trigger volume is changing or possibly getting a trigger event from the doors moving?
Is the trigger volume some how attached to something that is moving?
Do the doors opening possibly move the player (push,physics etc etc)?
Do you have you tried debugging right at the end overlap so poke around and see if there’s something happening in the scene very fast like the player popping or the trigger volume?
