Flashy video playback and a lots of error messages on m1 studio max

Hi,

I'm using the latest version on the M1 studio max for a few weeks until today it was fine, now I started a new project and premire went crazy. BUT I started to see this flashy playback problem last week, no matter what footage I gave him it starts to change the exposure. Drive link to the problem: https://drive.google.com/file/d/13usb4LCvXI2nuSfD_a396TRlI_PML970/view?usp=sharing 

This flashy thing stays on even after export. I onyle managed to export on a different pc to get rid of it, the project file was ok, just opened it on windows and exported without any problem.

My other problem is that I got a million error codes, and dont know why. And my mac today started to generate apart from the .pek files, which still dont know why do I have to see, .mxfindex files as well, so now my contet folder is a complete mess.

Here you can see, that it started to flash the waveform thumbnails, which are mostyl empty btw.

What happened to my premire in the last few days? I did not updated anything, I thought if I switch to mac it would be stable as hell :((((

Pl help, this weekend I need to do 3 same day edit, dont have time to troubleshoot problems like this :(((
