as a new user I was quite lost at the beginning
I understand the situation, it's normal for first-time users to be a little confused at first, but you'll naturally notice that Recalbox is easy to set up.
Could be nice to have in the wiki some advice in this regard.
but I haven't seen any similar reports from another user.
It's not that common, that's why there is no such warning.
But, @pitch64 "El documentator", what do you think of this?
For example I also disabled the "rewind" feature that I heard some users also had issue with it.
This depends on the hardware and console, but we have a warning for this in the documentation:

And even in the official youtube video tutorial:
