Might be two reasons, one is that an antivirus is still trying to scan it for malware. It has none, but a lot of antiviruses give 0 damns about your PC, and take 100% of power to "scan". So, if you are using one, try and open the game once more.
If it continues to appear, I am afraid that it might be that you are not meeting the lowest required specs for the game, they are listed below.
- Windows 10/11 (64-bit)
- Quad-core (e.g., Intel i5-6600K / AMD Ryzen 3 1200)
- DirectX 12-compatible (e.g., GTX 960 / RX 470 or integrated Radeon Vega 8)
- RAM: 8 GB
It may also help to update your graphics driver. Sorry for the inconvenience :(
