"Generating preview" issue causing lag and delay

When working on a GroupShare project, every few segments the message "Generating preview" appears in the bottom bar and freezes the program for a minute or so.

Imagine my frustration when working on a long project and I have to wait a minute every few segments.

And it seems that this issue has been around for some time now with older versions of Studio too (I'm using 2022). How is this still not fixed? What is up with this preview problem?
