Always crashing when deleting object

In one map the editor always crashes when I delete any object.
It’s going to 100% in the “updating asset references” and then it dies.
In another map everything is fine.
Help! I can’t work anymore!
Thanks!

same problem here need a fix

Check to see if you have a duplicate map file, the same problem happened to me, and it was because a dup map was in there, even though it was named differently, ue changed the name to the same in editor

I did in fact have a duplicate of that map in a subfolder as a backup. But that was there for longer and the problem only happened later.

Little later, but now I have same problem with 4.25, I duplicate the problem map, and the new copy is working fine. If someone experience same problem can try this solution.

it works but if you have many sequencer you will face other issues, like you have to replace every actor in those sequencer!!! UE4 is pain in hell
