I can't launch the game from the launcher

As the title says, I can't launch the game anymore.

I play via steam on a wins 11 pc. I didn't have any trouble before around 5 months ago, the last time I played, but now it says my system cannot support this title.


Does anyone know how to troubleshoot this?

it means your CPU doesn't support AVX and without that support you can't run PSO2 anymore.
