Tutorial gets stuck.

I've seen posts about this here, some from years ago without a solution?

The Tutorial gets stuck at Tokens, just when you are supposed to open the Token Settings to rename it, but Settings simply doesn't open.

Also gets stuck if you hold left click anywhere on the VTT, the ping circle will come up and stay frozen, and now you are unable to move tokens, draw any figure or insert new tokens. Also, if its done before a part where the Tutorial was supposed to automatically add a token, it will not do it. 

BTW, you cannot finish the Tokens tutorial because of that, and Communications also seems to have the issue when you try to ping, because the ping also gets stuck. 

OK  the Tutorial "Text Chat" also doesn't work. Typing "/em waves" as it suggests, doesn't do anything and the Tutorial stops there. 

Curiously enough it does work on the normal chat of a game I'm part of, but not on the tutorial.

On the Tutorial "Page Toolbar" it freezes at "Hover over the page that has the player bookmark to access the Page Settings. Click the gear icon to continue".

I would recommend against taking the tutorial. It is very old and out of date, and at some point it will break. My suggestion is to check out the Learning Roll20 Course on Youtube, or my own video, Starting from Scratch. Additionally, starting your own test game to play with different features and controls is a great way of getting used to the software and layout.
