Jetbrains toolbox script path not available

I installed the nix package Jetbrains Toolbox. With the toolbox I installed pycharm, ClionNova and RustRover. When I want to launch them via the Gnome search, nothing happens. I also added the script of the toolbox to my PATH (requires some bash soft-links) but when I want to launch for example Pycharm from the terminal I get the following error:

$ pycharm
/home/mobergmann/.local/share/JetBrains/Toolbox/apps/pycharm-professional/bin/ line 175: /home/mobergmann/.local/share/JetBrains/Toolbox/apps/pycharm-professional/jbr/bin/java: cannot execute: required file not found

Why is that and how can I overcome this issue?
