"Process shell finished" on Windows

[Galen Boyer]

I am on Windows 10 Enterprise running Emacs 27.2 but this also happens
on Emacs 28.2. M-x shell and now I have a buffer running shell. I then
issue a command that calls some script/executable etc. It runs
successfully but then when it is complete I see that the command.com
process has been killed.

What I'm showing here is calling cygwins ls.

c:\GITHUB\edm>ls -la
ls -la

c:\GITHUB\edm>
Process shell finished

So, then I M-x shell and get it back

I originally thought that something about cygwin was an issue. But it
also happens when I call other executables, but not all of them. For
example, if I execute windows scripts, it is fine.

c:\GITHUB\edm>dir

When I execute something like python, it is fine as well.

c:\GITHUB\edm>cd Python/
cd Python/

c:\GITHUB\edm\Python>python terra.py --help
python terra.py --help
usage: terra [-h] [-V] [-O] [-P] [-S] envName

Spew commands for spinning up projects

positional arguments:
envName

options:
-h, --help show this help message and exit
-V, --vmbool Do we need to spinup a VM
-O, --vmonlybool Just the commands for VM
-P, --printfunctionnamebool
Print the function names at the beginning of the
commands
-S, --sbxbool Is this a sandbox?

c:\GITHUB\edm\Python>

Any ideas on what I should do, look into, debug?

Thanks in advance!
