anipose label-3d slows down after the first video

[nehashiokami]

Hello everyone, I am using a PC with windows 11, and the GPU is GeForce RTX 3080 Ti, driver 31.0.15.5123. Everything seems to be going well, until I try to create labelled videos with anipose label-3d. The first video gets labelled pretty quickly at ~12it/s, and but the subsequent ones go at 1-2it/s. If I interrupt the process with Ctrl+C, and restart the video that was getting labelled at 1.3it/s, it re-starts at 30it/s and completes at 9it/s, telling me that the video was labelled at 14it/s. The next video it tries to label starts at 9it/s and it/s keeps going down. Does anyone know what could cause this type of slowdown and how I can avoid it?
