Issue PHP Composer isn't working

[Mann87]

Hi, can it be that PHP Composer in Plesk Obsidian Version 18.0.21 isn't working? My System is a CentOS Linux 7.7.1908 (Core)‬, PHP Settings 7.3.12. If I try to click the button Go to the application folder [change] and I select something from the list nothing happens. Also Mode change isn't working. And no way to do a search again.

I now reinstalled the PHP Composer Extension (Version: 1.0.2-167) then I can do a new search run, but that also don't help. It find my composer.json files. But I still can't select or click anything.
