Sequencer in 5.4.3 crashed

UPDATE: I’ve discovered that it only crashes when I have the level sequencer tab open when I hit play. So, as long as I have my code connected and do NOT have the sequencer tab opened when I hit play, it runs through and works fine, I hit exit and it comes back out as usual, no crash.

However if I have the sequencer tab opened as if I’m making edits and hit play, it will play fine until I hit exit and then will crash. I dont know if this is an error on my behalf… (Cant see how considering it’s never been an issue in the past?), or if this is a bug. I’m leaning towards a bug, because I also noticed despite my previous comment that it will still crash even when I have the level sequence player code disconnected and am using animation sequence instead so long as the level sequence tab is opened. Seems like a bug to me.
