Resolved [1.0.0-exp.8] Entities Hierarchy window completely broken

Entities Hierarchy window currently is completely broken at my production project. It just stuck at loading forever. Seems like it's over the text length limit. Can official point me the code to hotfix this bug?

Spoiler

I ran into the same issue. Some of my game objects had names that exceeded the FixedString64Bytes limit that the entity hierarchy window imposes. Shortening the name of the game objects fixed the issue for me. Not sure if there is another workaround.

 

Same issue here, I have thousands of assets that are generated by users with long names, is there a way to workaround this without renaming all those assets?
