Premiere Pro Poor Performance

Hello!

I am really in need of some help. For me premiere pro has been running smoothly and perfectly on my PC ever since i've had it. I got an RTX 3080, 32GB RAM and an Intel I9 10900K. Like I said ever since i've had this PC (about 3 years) it has run perfectly and now just this week I am having really bad performance issues in premiere pro. It is not responding often, it is really laggy and choppy on iot's playback, my audio track runs but my video track is frozen. I have never experience anything  like this at all, my games run as perfect as ever, everything does but premiere pro. I have deleted my media cache, updated my graphics card, turned my play back quality down to the lowest, accelarted my GPU. I have done everything I have seen in articles and videos to help optimse performance but it hasn't helped at all. I have no clue what the problem is in my task manager, my CPU, memory and GPU are all running at like 30% thet aren't maxed out or anything. The only problem I have noticed is that my GPU isn't quite encoding or decoding that well. Please someone help me, i desperately rely on premiere pro daily.
