The same goes for me. I bought a new computer last week with modern hardware (AMD Ryzen 7 3800X, 32 GB RAM, NVIDIA RTX 2060 6 GB GDDR5).
The game just starts for a second and then closes itself again. That's it. No error message, nothing.
I had a look into the Windows Application Event log.
There's a crash report. It points to a log file on the disk.
The log file shows a fatal error with the UnityPlayer.dll
It seems that the game uses a quite old version of the Unity Player which doesn't seem to work on my new PC for some reasons...
If I try to replace the Unity Player with a newer version the game states that it was compiled with a different version, so that's not an option either.
Looks like I have to drop this game...
