Long wait Loading.LockPersistentManager when loading scene

I was profiling my scene load, and there’s a non-trivial amount of time spent on a single call to Loading.LockPersistentManager:

Does anyone have more information on this? I read a post that made is seem like this was an avoidable thing if I do my scene loading correctly, but so far I can’t get rid of this significant delay. My scene load approach is to LoadScene my simple “loading” scene, then LoadSceneAsync the real scene. Anyone else getting hit by this delay in their loading? Is it just part of the loading process?

I’m having the same problem. 2019.3.13f1.

Bump. Voted!

I just experienced this issue on 2020.3.26f1. The annoying part is, I can’t figure out how to isolate it. It doesn’t seem to be one specific scene or object being loaded. Does anyone have any info on this? The issue was marked as resolved on 2020.2, but it clearly is not.
