I have managed to reproduce this as well, we are working on a fix!
Kind regards,
Markus
The issue as it seems for your specific installation was that Hub was not able to read the files in the Community folder for MSFS2024, I can’t tell exactly why this happened, the filesystem just reports an unknown error. However it looks like it does now work for you and all packages installs properly? Please confirm 
Kind regards,
Markus
I have the same problem. All is OK with FS2024, but it’s impossible to install the base packages on FS2020.
Any fix yet?
