I cannot start the application, and in windows event viewer it recorded the following messages:

It looks like something went wrong with .net runtime version? but I should have no missing runtime as my environment already installed all .net framework version 3.5-4.8 via visual studio installer.

Microsoft XNA Framework Redistributable 4.0 Install?

That's weird. I should have it installed before, but re-installing XNA 4.0 indeed resolved the issue. Thank you.
