Video skips for about 2 seconds and returns to normal

Hi, 

I'm having trouble with a video I'm editing. There's like a couple seconds where it'll get real choppy and laggy, but then will come back to the original frame rate. I have the Dropped Frame Indicator on and it doesn't say anything is wrong, and when I view the original unedited clip in VLC, the choppiniess is not present. This is Premiere Pro 22 (Build 169). I believe I have it set to "same as project" Here are the clip properties.

It's a Desktop capture from OBS. I have other clips that are a frame rate of 24, but they aren't right next to each other. Would that be causing it? I also have GPU Acceleration on, and if I turn it off it gets worse, so that's not it. I've tried clearing the cache, and resetting preferences, but no joy.  I have playback resolution down to 1/4 and it still does it. I'm stumped.

Try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.

I don't know why, but creating a new project seemed to work. Luckily I wasn't too far into the old one, so it was easy to reconstruct.
