After Effects shows green RAM preview but doesn't play proper framerate

I am experiencing an issue where no matter how many times I play back my timeline, it doesn't play smoothly - even though the RAM preview bar is green. I've purged all memory and cache, restarted AE and the computer and this problem pops up every now and again. I am running CC 2022 and have 700GB of SSD space allocated to the cache while keeping AE and project files on 2 separate other drives.

This didn't seem to be an issue for me in CC 2020.
