Rocket League night of new season, randomly now has windowed border and bad frame drops.

[GamingStool]

I never had an issue like this ever. The night of the new season (12/6/2022) around 8pm est, when I went to open rocket league, it opened with a windowed border(as seen in the attached image). The same time this happens, I think its odd but I start playing a game. Extremely bad framerate like something Ive never had with this PC. I have a VICTUS HP nvdia geforce rtx intel core i5. I dont know the specs beyond this. What would be the issue? Why is this randomly happening now, the odds that it happened right at the last day of the season? What can I do to solve this? The game is unplayable right now with the frames the way they are, although compared to yesterday, it seems better today. Still bad.
