Play/pause frozen

HELP!

I don't know what's going on.

Until last week I was using Premiere with it playing the mini player a lot. So what I did was buy a 2TB SSD and 16GB of ram. I installed everything, reinstalled Windows (Original) and now the program opens quickly and runs more smoothly.

PROBLEM: I'm working in Premiere, and suddenly Play/Pause stops working, leaving the FUNCTION stuck. If the video was rolling, it continues. If it was paused, it remains paused and I can't play or pause it. The program kind of locks the play/pause function.

I can walk through the program, I can save, I can add elements to the timeline, but I can't play or pause. The button does not respond.

What can it be???

Please help me!
