I have my /tmp mounted as noexec for security reasons. Regardless of that there should never an executable run from /tmp this is a bad practice and can lead to issues. Instead I suggest using .cache/opentui.

That is not something opentui controls, that is a Bun issue with standalone executables, which extracts bundled libs to that dir and tried to dlopen from there.
