Audio Stutter after rewind

I also use Cubase 11 Pro to practice cover songs for a band. I have over 70 tracks of audio mp3s loaded in one project

No inserts or sends - not even EQ on the tracks.

Every time I “rewind” - and restart the playhead the sound drops out 4 or 5 times before it starts playing smoothly.

PC is Windows 10 Pro with 12GB ram and Nvidia graphics card.

Any idea what’s causing this?
