Can't upload because of some copyrights etc...
But the book (Mastering Windows Server 2019, 2nd Edition) has 9.15MB and it has about 500 pages.
I've downloaded the epub from #1846886 - similar situation - but the book was opened after 10 (or more) minutes. But the book preview is unresponsive (high CPU usage of QTwebengineprocess), if I want go to full screen - app is freezing.
On previous version of Calibre everything was fine, app was fast.
