Installation to STM32CubeIDE fails

[lrademacher]

I am trying to install into STM32CubeIDE (https://www.st.com/en/development-tools/stm32cubeide.html) Version 1.16.1.
I am on Windows 11 (64-Bit).

Install fails with:

Cannot complete the install because one or more required items could not be found.
Software being installed: Assist AI 1.0.2.202405061907 (com.github.gradusnikov.eclipse.assistai.feature.group 1.0.2.202405061907)
Missing requirement: assistai-dependencies 1.0.3 (com.github.gradusnikov.eclipse.plugin.assistai.dependencies 1.0.3) requires 'osgi.bundle; slf4j.api 2.0.12' but it could not be found
Cannot satisfy dependency:

I tried both: Marketplace and "Install New Software".
In "Install New Software" i also unchecked "Contact all update sites during install to find required software".
