So I try to open it again 2, 3, 4 ... times, and then it starts normally.
Because?

Page

says to delete the tird parts plugins directory and the system directory.

But where are these directories located?

Here is the contents of some of my configuration directories

$ command ls -1 ~/.local/share/JetBrains/PhpStorm2020.1/ ~/.config/JetBrains/PhpStorm2020.1/
~/.config/JetBrains/PhpStorm2020.1/:
codestyles
'Composer Log'
disabled_update.txt
eval
fileTemplates
inspection
keymaps
options
phpstorm64.vmoptions
port
port.lock
scratches
tasks
terminal
workspace

~/.local/share/JetBrains/PhpStorm2020.1/:
availables.xml
availables.xml.etag
extensions.xml
pluginsXMLIds.json
pluginsXMLIds.json.etag
rest

But where's the tird parts plugins directory and the system directory?
