Using a subprocess is always the wrong thing to do. Just import it or use runpy.

You can only use the embedded python environment that exe uses from exe itself.

So if you absolutely must use a subprocess, then you need to re-design your program to accept arguments that switch it into "script running mode" (for example, --run-script <script-path>) instead of running your main code. This script running mode then loads the script and executes it. In your main program code, you should spawn the sub-process with [sys.executable, '--run-script, path_to_script]` as the arguments. See https://github.com/orgs/pyinstaller/discussions/5978#discussioncomment-971765 for a proof-of-concept example.

But do note that such external sub-scripts do not undergo import analysis, so you will need to manually specify all its imports as hiddenimports, otherwise they might not be collected (i.e., if they are not imported elsewhere, for example in the main application script) and will end up missing.
