Addon fails to update

What could be the reason i am getting these errors?

I get them both on libreelec as a win 7 machine, both do have the addon already installed.

I just install addon by zip and get this.

If I reboot and first thing I do is install the addon, then it worksConfused?

Can I fix this somewhow?
