[Pri 0] Live edit causes CPU freezing (regression)

Summary

I am only marking this as urgent because I feel this may cause hardware issues to creators building content. I noticed when launching live edit, my CPU will peak at 100%, and it happens 6-7 times. This makes my entire PC freeze, even the mouse cursor (which no other software can do, the PC is brand new and really powerful). Reference ID attached.

What Type of Bug are you experiencing?

Stability

Steps to Reproduce

Launch live edit in project shown in reference ID

Expected Result

No CPU peaks and PC freezing when launching live edit (like before)

Observed Result

CPU peaks at 100% for a split second, and PC completely freezes around 6-7 times when loading live edit. This happens 100% of the time when loading live edit.

Platform(s)

PC

EDIT: Seems this happens on the initial loading of live edit, and not when pushing changes (so it’s not 100% repro as mentioned above)
