I have had the following problem for a few years now (therefore different versions of Illustrator, let's say from 2020-2023).

When I start Illustrator, opening the first (I specify the first) document that is an Empty table or an already existing document that Ai takes an exaggerated amount of time! Then, after this step, the other documents are opened in normal times.
This happens to me from different versions of the software, and it also happens if I close the software and restart it to open a document, or if I start Ai after restarting my computer.

the hardware is the same. It's not brand new but it's not slow either.
windows 10 x64, i7 4.0 ghz serie 4000, 32gb RAM and ultra-fast M.2 hard drive.

Help me.
