So I did a bit of research and from my quick results, it seems like that the version of .NET of this game depends on an older version of OpenSSL, which are incompatible with the newer ones distros package.
So, updating the game with a slightly newer version of .NET (does not have to be a major update afaik) should fix this?
Alternatively you could try installing the openssl-1.0 or 1.1 package and run the game again (some distros should have that as a separate package available for backwards compatibility).
I did not verify this myself yet, but it might be worth a shot.
