Nuendo 13 stops music playing when I move the video player,

Hello, can someone help me solve this problem? My newly installed system is Windows 11 Professional. Now I have two problems that make me very confused. 1. The audio file can’t be dragged into nuendo, but I found a solution through google and changed the value in the registry. I just wonder why these problems need us to manually modify the registry, can not be set by default.2. When I am doing music or sound design for a video, I only move the video window while I am playing, or adjust the volume fader, or any other Vst or plugin parameter, and the music will pause and return to where it started. It’s like I pressed the space bar myself. I tried reinstalling nuendo and running it as an administrator, but compatibility mode (flash back) didn’t fix the problem. google couldn’t find the same thing. My sound card Settings were fine, and I could switch to another web page or app while playing, and the sound wouldn’t stop. It’s when I do something inside the Daw that I have a problem.

I tried to re-establish an account under Windows 11, and at first everything was normal, importing audio or moving the video window when playing is normal. But a few hours later the problem started again.
