Which OS are you using? Certain operating systems break Erlang into several packages, you need to make sure those packages are installed.

Will adding :observer and :wx be problematic for production releases where we are not installing the underlying wx libraries as part of our docker image?

I am having a similar problem, I am using Sonoma 14.1.1 (m1), erlang 25.3.2.7, the issues boils in my case down to wxwidget compilation with erlang. I have not been able to compile erlang passing the --enable-wx --with-wx-config option.
it keep failing with the next:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [../priv/aarch64-apple-darwin23.1.0/erl_gl.so] Error 1

There’s a hacky way to start the observer application, even if it’s not part of your extra_applications.
The only requirement is to have the wx and observer modules compiled somewhere in your system.
Load an IEx session that knows about wx/observer. It’s a plain iex call in my case, e.g. not iex -S mix.
Having the IEx session open, figure out where the compiled modules are:
iex-without-mix> :code.get_path()
[
#...
~c"/Users/username/.asdf/installs/erlang/26.1.1/lib/wx-2.3.1/ebin",
~c"/Users/username/.asdf/installs/erlang/26.1.1/lib/observer-2.15.1/ebin",
#...
]
Go back to the iex -S mix session and add those paths:
iex-with-mix> :code.add_path ~c"/Users/username/.asdf/installs/erlang/26.1.1/lib/wx-2.3.1/ebin"
true
iex-with-mix> :code.add_path ~c"/Users/username/.asdf/installs/erlang/26.1.1/lib/observer-2.15.1/ebin"
true
Now we can start the observer application:
iex-with-mix> Application.start(:wx)
:ok
iex-with-mix> Application.start(:observer)
:ok
iex-with-mix> :observer.start
A fragile automation with ~/.iex.exs file:
:code.add_path(~c"/Users/username/.asdf/installs/erlang/26.1.1/lib/wx-2.3.1/ebin")
:code.add_path(~c"/Users/username/.asdf/installs/erlang/26.1.1/lib/observer-2.15.1/ebin")
Application.start(:wx)
Application.start(:observer)
Having the above lines in the ~/.iex.exs file, allows a freshly started iex -S mix session to launch the observer with just the :observer.start() command.

Did you try the options listed here: Observer in iex -S mix error: (UndefinedFunctionError) function :wx_object.start/3 is undefined - #5 by axelson?
