Why can't I switch user?

I have an ubuntu desktop vm on VMware workstation.

I can connect to it with one of my user. Here LoukMouk.

When I try to use the option switch user situated at the top right corner of the GUI, it doesn't send me to the page to choose what user I want to connect as... Its like it only locks my session waiting for me to enter my password.

I don't know why... This doesn't always happen, sometimes, when I try a second/third time, it finaly shows me the selection...

Is it possible that my limited amount of ram could prevent me from opening a second session? I mean... It works sometimes... I'm confused.

Am I the only one having this issue? (:

This has already been asked: Switch user not working in 17.10

As the answer to that question says, this is a bug in GNOME. Meanwhile, you can hit Ctrl + Alt + F1 (with fn if needed) to go to the login screen and switch the user.
