After installing plugin and restarting NetBeans NPE comes up

[Chris2011]

Description When I install the plugin for the first time or after removing it and adding it again, I need to restart the IDE. After restarting, I see that there is a process running "pylsp dependencies". After couple of seconds there is a NPE coming up (see section "Mandatory logs")

Steps to reproduce the behavior:

1. Install python plugin
2. Restart IDE
3. Look into the statusbar to see the "pylsp dependencies"
4. Wait couple of seconds and see the NPE inside the notifications.

Expected behavior There shouldn't be an NPE

Desktop (please complete the following information):

• OS: Windows 11 64 bit
• JDK Version OpenJDK 14
  • Netbeans Version: 17
  • Python Plugin Version: 2

Mandatory Logs

After installing the plugin and restart NetBeans it will install the pylsp dependencies and after some seconds I got an NPE:
