Couldn't launch applications (Broken pipe & ERRCONNECT_CONNECT_TRANSPORT_FAILED).

Describe the bug
Tried to install cassowary in https://github.com/quickemu-project/quickemu based vm.

The GUI connection & application listing seems to work, but shortcuts created never launches... If ran from cli, following error is thrown:

python3 -m cassowary -c guest-run -- 'C:\\Windows\\System32\\mspaint.exe'

To Reproduce
Steps to reproduce the behavior:

1. Install quickemu (just shell script with depends: qemu jq python3 spice-gtk wget zsync xrandr swtpm)
2. Run quickget windows 10
3. Add extra options (windows-10.conf on same directory):

   cpu_cores="4"
   port_forwards=("7220:7220")
   

4. Setup on windows as explained, change RDP port to 7220 under VM (instructions on settings itself).
5. Setup on host: VM IP: 127.0.0.1 and Windows Hostname and Username/Password from looking at guest.

Expected behavior
The application should obviously launch without the ERRCONNECT_CONNECT_TRANSPORT_FAILED and broken pipe error.

System information:

• Cassowary Linux client version: [run python3 -m cassowary -h to find version ] 0.6A
• Cassowary windows component version: [run "C:\Program Files\cassowary\cassowary.exe" -h to find version] 0.6A
• Linux Distribution: [e.g. Arch Linux] Void Linux
• Windows/Edition used [e.g. 10/enterprise, 7/ultimate] 10/Pro

#93
In a word, try adding /sec:tls to extra RDP flags

@KyleUltimate It didn't work out (almost no change):

Another thing worth mentioning is that if you merge this PR, you should update the instruction for Windows VM and tell users to disable Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended) in Remote Desktop settings
Did you also do this?

[Animeshz]

Had that turned off already 👀
