In my QGIS 3.20.2 I can't use tools from the Vector menu as I used in the previous QGIS version. See the print screens. Can somebody tell me why as well as how to resolve this issue?

Try to tick the Processing (it is a core QGIS plugin) from the Plugins > Manage and Install Plugins



I found out the problem - it was Settings - User profile.
