my play button not working

[neverendfriday]

I wonder if anyone knows about this problem,
so I'm posting a question here.
I'd like to apologize for using the translator.
I'll post a gif here.

As you can see from gif,
I pressed the play button once and this should not stop unless I press space bar.

But it stops automatically. Even if I don't press anything.

I initialized the PC today because of this problem.
I'm using the 2021 version of Premier Pro.
If there is anyone who can solve this problem,
I would appreciate it if you could let me know.

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 install 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.
