So I made a thread here which no one replied to, just want to share that I fixed it by clearing every ini file (backups by SPIni) in mod organizer and my games/skyrim folder. Now I no longer get ctd on almost so many things I was trying, I did so many things like update windows, check for disk integrity, verify game files on steam, change sounds properties and so many other i've read (except reformat pc) and this fixed it finally :) I remember deleting those INI files before but I didn't delete the backups and now my skyrim works
