Default Crackles while export

Hi,
I am really frustrated... I tried to export my master litterally 50 times today and everytime there are random crackles in the exported file.
My performance is something around 20 percent, all vsti are rendered. I have 10 songs (around 40 tracks per song) separated with regions
I have absolutely no issues while playing back but only when I export the songs.

I run the newest version of reaper on a Mac pro,
I tried several buffer sizes up to 4096 but it seems it's getting worse. All files have the same sample rate and I export in the exact sample rate.
I render online (because I have some outboard gear for mastering) on highest quality

Any ideas?

i am about to rage quit reaper and switch to another daw... i wasted hours double checking and re-exporting songs. even if i export the mix first and master the stereo wave afterwards.

just checking that you have seen your RT CPU usage? Your pic is only showing CPU. (you need to right click the performance meter to view additional options)

This seems strange to me. I know you mentioned trying an online render.
Do you get the same issues if you try a "save live output to disk"?

RT CPU is constant at around 75%
