Audacity 3.5.1 bug

When I add an mp3 file and press play, nothing is heard even though I have the sounds from my computer on. Before this new version everything worked normally.

Have you selected the correct Playback Device?

Do you see the waveform?

Is it only MP3s? Just this one MP3?

I have just this evening installed 3.5.1 and all seems working perfectly. Windows 11
But I like a clean start, so I completely uninstalled the old version 3.4.2 first.
Also I installed the version with no addins.

Yes, now it works when i change playback device. The latest version had changed that setting by itself. Why do updates change settings by themselves?
