Setting the default RHI for Windows to DX12 and enabling Forward Shading results in a crash when adding a texture sample parameter to a material.
Found in 4.22 CL# 5660361 and 4.23 CL# 6074473
Working as expected in 4.20 CL# 4369336 and 4.21 CL# 4753647
Results:
The editor will crash
Expected:
The TextureSampleParameter2D node would be added to the material graph
