Jetbrains App's desktop files (*.desktop) in your user local directory are required to be in the usr public directory.
Open the terminal and execute the commands below:
cd ~/.local/share/applications
sudo rm /usr/share/applications/jetbrains-*
sudo cp jetbrains-* /usr/share/applications
Check new icons using Windows start menu search bar.
Note: these commands are required in every major update (or if there are icons changes in minor updates).
