Lost features after 2022.1.2 update

Since the last update, CSS management in PHPstorm does not work correctly anymore. 
- no more code completion (CSS classes), no more color preview in the gutter...
- endless message "Analyzing..." (top right corner) for all files (any type)
I tried to reset caches, without success. 
Rolling back to version 2022.1.1 : same problem
Config: MacOS Monterey, up to date
Any idea ?
