Problem with game freezing up while loading a move

[HORSE JUMPSCARE]

So every time a character throws out a new move with some effect attached to it, like Sol's Gunflame or Anji's fan super, the game freezes. It just stops dead in its tracks for a few seconds with no audio, and then continues afterward as if nothing happened. While my computer can handle GGS at 60 FPS on max settings, it does so at like 99% CPU usage, which I would expect to be the core problem, but I have no way of knowing. I don't think it's a problem with my game location, as I've had this problem while the game was on both my SSD and HDD. I know the problem isn't the drive going to sleep mid-game, as the problem can occur a few times in the span of a few minutes.
This happened to me in the network test for accent core +R as well, but the network test still deemed me acceptable. Hell, this has happened to me in other games entirely, like Dead By Daylight and Knockout City. I've been avoiding going online because of this problem, as it's annoying for both me and my opponent.
So far the only other time I've seen this bug happen was for some twitch streamer who had the connection freeze when he used Gunflame. I haven't seen or heard of this from anyone else at any point, but if anyone has some advice, I would GREATLY appreciate it.
