I don't have the answer to your circumstance; the Standalone Builder is
complex, and LC's introduction of stack name conflicts not inherent in
the MC engine has become such an ongoing issue that it might be ideal to
revisit that sometime*.
In the here and now, I have only one tidbit to contribute which may or
may not be relevant: stack name conflicts can appear when the path used
to open the same stack file is different in different contexts.
This confirmed behavior is noted in this bug report from 2015:
https://quality.livecode.com/show_bug.cgi?id=14583
The example there is uses two paths that differ based on the Unix
shortcut of "~" for the user's home folder, e.g.:
/home/matthias/workfolder/somestack.livecode
...vs:
~/workfolder/somestack.livecode
Both paths refer to the same file system object, but apparently the
engine maintains its handle to the file based on the given path rather
than the fully resolved path, so it believes those are two different
files in which the stack objects happen to have the same name.
So you might consider double-checking code to see if you use any
relative path, or shortcut form, in your scripts.
But given that the same scripts worked well just a couple days ago,
presumably with no changes to file paths in your scripts, this tidbit
may be merely mildly interesting but irrelevant to the problem you're
facing.
* On stack name conflicts see this enhancement request, and follow the
link in Comment 20 there for details on the underlying engine limitation
which gave rise to the issue:
