Open Project in DevContainer - Failed to get an IJent binary for Linux X86_64

Hi,
I'm just trying to get a Linux devcontainer running under Windows 11.

The container starts fine and I can use the terminal. 

However, the backend does not start - the log contains that error:

I didn't really see anything suspicicous in the log before that.

I already tried using a different internet connection as this is sometimes an issue in my environment, but to no success.

I can provide more information, but I'm not sure what would be helpful here.

Thank you for your support!
