Unable to run hello-world

I was going through docs

After mix atomvm.packbeam i get:

21:29:26.362 [error] Process #PID<0.236.0> raised an exception

The exception happened while checking this code:

elixir and erlang versions (asdf)

cat .tool-versions

erlang 27.3.4.3
elixir 1.17.0-otp-27

this looks weird, can you you try and remove your _build folder and go again, also it stands out you are running elixir 1.17.0 maybe try with 1.17.3..

will try to replicate something locally..

[mordv]

can you you try and remove your _build folder and go again

Yep, that worked. Thanks!

But still I think thats a bug. Before trying asdf I was facing #57 - i.e first mix atomvm.packbeam was run on OTP 28 - that might have somehow messed up with _build.
