Audio dropout in track even when plugins turned off.

Hi i was wondering if anybody else has had this issue?

I have FL studio 21 latest version and parts of my track have a weird audio pop and the sound ducks out for like a second.

I have 2 links of examples. One is from a project with lots of plugins and automation etc going on. but the other clip is just a kickdrum audio sample no plugins etc and the same weird audio pop occurs.

I can share my audio settings and export settings im using. I use a focusrite saffire 212 and reinstalled the drivers

in this first link you can hear the issue im talking about at 25 seconds.

in this next link its just a kickdrum no fx or plugins etc and the issue happens at 26 seconds.

It must be some kind of audio issue if its definitely not a plugin causing it i guess??
