Help Needed-RP 4B/File editor failed to install addon

Newbie, I have tried many times to switch to Home Assistant but with no knowledge of programming, I gave up. Now trying again, got as far as trying to load File Editor, it fails everytime.
Working for the Graphic UI on Windows 10 via the IP address:8123

I have tried various versions of Hassio all the same result.
The message is:
500 Server Error for http+docker://localhost/v1.40/images/create?tag=5.2.0&fromImage=homeassistant%2Faarch64-addon-configurator: Internal Server Error (“Get “”: context deadline exceeded (Client.Timeout exceeded while awaiting headers)”)

See photo image

I cannot find anything that looks like a solution.
Has anoyong got a solution and if so, can you please, please give me an idiot proof step-by-step instructions.

Thanks in advance for any sensible suggestions, please do not tell me I have to go and learn programming(:smile:

Hi Eugene, i’m facing the same error. How do you finally managed the install?
