Activity monitor show cpu taking massive load after running simulator from Xcode

As you can see in the image, it seems to coming from the Xcode simulator, specifically, the assets aspect of it. I have around 250 pdf images that totals up to less than 7 MB. I have a MacBook Pro M1 32 GB and for the first time since buying it, the fan starting whirring loud. Any help will be appreciated. Thank you. And also sometimes 2-3 of those "AssetCatalogSimulatorAgent" pops up.

same issuse,looking for reply
