Performance issues Cubase 12.0.20

all was fine till yesterday ive opened one of my project,
the CPU performance meter was stuck on max, only disabling some uad plugins release the issue
and it comeback after project restart, I’ve tried reinstalling Cubase and some other plugins, playing with latency and whatnot… sometimes what helps is to activate latency compensation, anyway Cubase 11 didn’t had this problem at all

also cant resize the small window of verusti plugin, crushes when trying to resize
