Sudden FPS Drop and Glitching in Twinmotion with SketchUp Imports – Anyone Else?

I’ve been using SketchUp for garden design and then importing the models into Twinmotion for rendering for the past three years. It used to work smoothly, but recently, I’ve been having problems while using TM2024.1. The files start glitching, and the frame rate drops to 5-8 FPS after just a few minutes, even when the file isn’t that large. I’m using a high-spec PC, so I’m not sure what’s causing this issue. Could anyone help? Is anyone else experiencing the same issue?
