Hola! Si lo que te pasas es que aparece la lechuza y de ahi se sale, el problema es conocido. La solución más directa es desactivar el wifi del laptop y con eso entra. Si quieres una solución sin desactivar el wifi, estos son los pasos (a mi me funcionó):

"This issue is related to a bug in OpenSSL 1.2. Any game that currently uses this version will have issues, this includes Unreal Engine 4.21 which is what Post Scriptum runs on.

Until we have a permanent fix, we have a workaround that should let the users affected play the game. You can find it below.

Step 1. Open "Control Panel" by searching for it in Windows search bar, by pressing the Windows button or key.
Step 2. Go to "System & Security"
Step 3. Go to "System"
Step 3. Press "Advanced system settings"
Step 4. Press "Environmental Variables"
Step 5. Create a new "System Variable" (NOT USER VARIABLE)
Step 6. Enter the following into the Variable name box: OPENSSL_ia32cap
Step 7. Enter the following into the Variable value box: ~0x20000000
Step 8. Now press OK.

you may need to restart your system for the changes to take effect."

Saludos!

To fix this issue, you can right click the game in Steam, click properties, and paste the following into the launch options:
cmd /c "set OPENSSL_ia32cap=:~0x20000000 && %command%"
