Engine 4.3.4 Playlist Issue

I have been having issues with my Playlist and Sync Manager. Is started when I tried to sync my folders and the files took up a ridiculous amount of storage space on my hard drive which is 1TB. Many tracks which I knew were on the drive were now showing red snd unable to play. I went back and cleaned up my Engine OS Playlists. After trying to perform the Sync Manager, the massage saints I do not have enough storage space and my heard drive was in the Red. Engine OS kept showing that 3 files are still importing. I then rebuilt my OS Playlist to what I have in Serato. I erased my 1TB hard drive, reformatted it and loaded a few Playlists and the Synce Manager went well then my Playlist songs are Red again with showing waveforms, load to a deck and it gives the same message that the gile cannotbe found, but the songs play from the folder. This is really frustrating. All my playlist are gone even though they show that they are there. https://youtube.com/shorts/DYN4vSPOvGo?si=SboReuUurRCmA4ej
