What is Unity.Sequences.SequenceAssetIndexer????

Can anyone tell me what this is all about? After my project loads, this pops up and takes at least several minutes to clear up. Any help would be appreciated.

Did you ever get anywhere with this? I get a 15-20s delay from this every time I compile. I have three sequence timelines in my project and they are tiny. What else is Unity.Sequences.SequenceAssetIndexer used for?

If anyone else ever finds this, I was having long delays every time I refreshed the project. I found a function in SequenceAssetIndexer (I’ve deleted the package and can’t remember the name) that creates a list of prefabs and checks to see if each one has a sequence attached. I believe the intention was to save this file to the PC but in my case I could never see the file being saved. I had over 9k prefabs in my project so this took a long time every rebuild. I removed the Sequences package instead of continued debugging.

Has this been fixed yet? In my scenes this caused constant high cpu usage making the editor unusable. Any workarounds other than removing sequences? ( I just need the editorial track from sequences )
Is it possible to duplicate the editorial track and only use that code?
