Anyone got a suggestion on why this is lagging?

I just can’t understand why this is lagging all of a sudden. Only happens when I create a new verse script.

my specs are:
NIVIDA GeForce RTX 4080
80GB DDR4 RAM
AMD Ryzen 9 5900X 12-Core Processor

The editor only utilises 12% on cinematic. So I doubt it’s a spec issue. I attempted to run it on low, and the same thing happened. This has only started to happen after the recent update
