Resolved [Particle System] Sub Emitters are making editor unresponsive for several minutes in 2021.3.17

Using editor 2021.3.17, my issue seems really well related to those ones :

https://issuetracker.unity3d.com/is...option-is-clicked-from-particle-system-preset

https://issuetracker.unity3d.com/is...-about-sub-emitters-of-particle-system-editor

Basically even when creating a new effect and trying to assign a sub emitter, when unity initiate it then it takes several minutes to get out of the Update Scene progress bar.

Any change to either of the particle system have the same effect. It seems like a regression as it does this even with older effects made under 2019 LTS.

Issue is the same wether I use the Particle editor or the hierarchy and inspector.

Any help would be welcome.

 

2021.3.19 LTS does not seem to show the issue, so if anyone face this, try to update
