I have this issue from time to time, and I'm a bit confused as to where I should find an answer.
I found some websites and a couple of threads here dealing with this problem, but I think my problem is a bit different.

Solo1959 has the problem every time.
It's a bit different for me. I can open several epubs, one after the other - no problem. Then one epub will take a bit over a minute, and the next time that same epub takes no time at all.
I can open an epub quickly several times, and then, for whatever reason, that same epub will be very slow to open.
I'm on Windows 11 Pro. i9-13900K, with 64 GB of RAM - my system is not underpowered.
Any ideas?
