Cubase 13 pro Freezes When Diasabling Tracks

Hey!

I am currently building a big template for my EW libraries.

1000+ (disabled) tracks. Had no issues at all until 700 tracks or so. From there, Cubase just started to randomly freeze when I disabled one or more tracks.

Does nothing until I kill the program through the task manager. I can then load up the project with no issues… until I disable something. then it freezes again. or not. just random.

The only plugin I have currently loaded is the vst3 version of Opus.

System:
intel i7 13700k
64gb ram
Powercolor Radeon RX 7800 XT Hellhound
Using Nvme SSDs only.

Anyone with similar experiences or a fix?
