wxWidgets error, and Program 'spirv/model_solid' with required defines not found

[Asher]

When I open a map or create one in Scenario Editor, I get a wxWidgets error (issue #9307). The weird thing is, I don't get it when I first open Scenario Editor. Also, when I am about to place certain buildings (in the actual game), I get a "Program 'spirv/model_solid' with required defines not found" error (issue #9315)
