Hello! This worked for me:

"FIX] Game crash in Intel 10th & 11th Gen CPU's.

Some players using Intel 10th and 11th Gen CPU's have been running into issues with the game crashing upon launch.

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."

This worked for me as well. I'm running 12 Gen i5 CPU. Thanks.

can't start the game, only splash screen with owl shows up

If above workaround didin't help you, there is another solution, less "nice", but effective too: disable wifi connection in your PC, you will be able to play the game.

Worked, thanks. 12th gen i9.

Did work for me as well thanks the value should be 0x20000000 (no ~)
thanks :-)

+1 for the fix - tried it - and now I can be shouted at by my co-driver/navigator again - cheers!

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%"
