Because even kalamatee already told you why?
"Yeah - I wouldn't worry about that build, it was expected to be broken. A
newer nightly should work correctly though." 
In Russian it is called "ПЦ". I cannot translate this concept into English so that it becomes clear.
The user has been trying to download the image and run it for a month and get the result: it shouldn't have worked!
Is it adequate? Nightly builds are usually much less stable than regular releases, but they run!
I can't imagine Ubuntu, FreeBSD or ReactOS nightly build not starting within a month and it is considered "and should not have"..
If it shouldn't, then it doesn't exist. Who can use it? Nobody.
So: False. YES, it does. There are tons of proofs
These aren't your proofs. I seem to clearly wrote what you need to do?
Don't show me what others people have done in the past.
Look at the calendar: what date is it today?
A nightly build is never a proof that something does not work, much less it does not exist. If you are a developer you should know that already. If you wanna test something, you must try a more stable version
The stable version of ABIv1 doesn't exist. Nobody is interested in ABIv1 builds made 3, 5 and more years ago. So I am trying to use nightly build. Which doesn't exist in the same way. Doesn't start = doesn't exist. You understand this perfectly when your formal logic is good.

Say: thank you paolo. How does this relate to the life of ABIv1 today (27-12-2020)? It doesn't matter.
So trying to deny the facts is just your speech, not reality. And for me this is enough waste of time or energy spent into childish arguments: do as you please. I won't maintain endless discussions in amigaland style.
Fact: you couldn't run nightly build and show us screenshot.

If you open the guinness book of records, you will find even more facts there. Only these facts do not concern us in any way. because for us - ordinary people, jumps of 3 meters from a place simply don't exist. I hope this is a clear comparison.
AROS-20201227-pc-x86_64 doesn't start:
https://youtu.be/nHH1AYRlBfkWho would tell you how and why to test something that doesn't start?
And how to switch to ABIv1? Let's say we want to do this: how?
