Bugs in 18.1 versions

Hi
I downloaded version 18.1
And I can't type the "/" character in the "pug" extension in quotes
example: ... ([routerLink] = "users, friends.id]")
I can't put "/" before the "users"
And also I can not copy the text and select a word by double clicking on it
And in addition, some files just do not open (for example, the settings of ".prettierrc.json" or converted html files from pug)
