Playback Doesn't Work

I've tried restarting musescore 4 and my computer and trying out different devices, but it just seems that nothing can play right now. Other software works just as fine, it's just this software. I have also tried to reset devices from I/O in preferences and even reset my preferences, but it still doesn't play any sound. In the mixer, it also shows that nothing is playing, as shown in the screenshot I took while a score is being played.

EDIT: it seems that it works now after I opened a new score file, so I guess the problem is solved.
