Having a Problem with dragging Videos onto my Timeline

Okey so,
Basically: in my Project Panel and in the Preview Panel my Video shows up completely normal
The Video is normal and all the audio is as it should be,
but as soon as i drag the Video onto my Timeline, it for some reason only shows the Audio tracks (so no Video at all), there blue and the quality is beyond bad.

I have no Idea why this is happening
First of all you should know i record in OBS on fragmented mp4 with multiple Sound Tracks to make editing easier

I tried pretty mutch everything:

Restart Computer (obusily) - didnt do anything

I went and changed my OBS settings to Record in mkv and converted it into a mp4 using OBS directly - nothing

I tried all kind of Stuff with Shutter Encoder like:
GoPro Cineform / DNxHD (just got a massive mov File)
Rewrap (gave me the mp4 i wanted but same Issue in the Timeline)
H.264 MP4 (somehow just put all the Audio Tracks into a single one but same Issue)

I also tried fixxing it with ffmpeg in the Console - still nothing

I Tried importing the Video into Premire in all kind of Ways - no change

I am completely lost and have no Idea what i should so

Im rather new to Premire so maybe this is an easy Problem and im just stupid but i dont know what to try anymore

So please if anyone can Help me, i would be really thankfull

Video normal in Preview

Blue / bad qulity / only Audio Tracks
