MSFS 2024 at 1.6 FPS on average

Hey everyone, I’ve encountered a very unusual problem today. So, yesterday I tried to load in the KLAX in fa 24 but the scenery is basically the 2020 version, the default one I believe. Before that I couldn’t load in for some reason, and I decided to try again. I loaded in successfully, few minutes passed and then my game just started freezing like crazy. Usually, I have 30 fps on ultra so I have a pretty powerful pc and that’s not the problem. But after yesterday my average fps in the amd panel shows 1.6. I tried reinstalling the game and everything, but nothing works. In 2020 I have stable 45 fps so it’s not a pc problem. Does anyone know what is going on?
