Premiere Playback bugging backwards, please help!

[HaiderHus]

So I have this problem since weeks and I thought it will go away from itself but it kinda got even worse. My playback is bugging back every second even if it is only audio. I tried so many "fix your playback" videos on youtube and they didnt help me out too. I have put a video to show you how it looks like at my premiere pro. Any ideas to fix that problem? I would really appreciate that.

Make new project and import old one.

See how it goes.
