I’ve encountered that time to time - maybe try reverting to even more previous versions of scriptplayer latest betas
Alternatively try using SLR interactive? Option 2 => https://discuss.eroscripts.com/t/how-to-connect-your-147-sex-toys-including-the-handy-fleshlight-launch-kiiroo-keon-or-onyx-for-interactive-2d-and-vr-step-by-step-guide/8275
Should be a more stable connection that route and there should be a hopefully better optimized playback algorithm incoming for Keon there
