System Information
Operating system: Windows 11
Graphics card: Intel

Blender Version
Broken: (3.2.2)
Worked: (2.79b, or if you open a file with a boolean from 2.79b in 3.2.2)

Short description of error
When using the bool modifier to make a cake cut of an object(ie. Show the texture through the object hole procedurally continuing) in "exact" mode, the cut region is not shaded, instead of shaded with the textured material. It only shades correctly in "fast" mode.
This happens if you create the Booleans and textures in 3.2.2 from scratch.
If you do the same thing in 2.79b, the texture properly shades in cycles in either carve or bmesh mode. If you save the 2.79b file and open it in 3.2.2, suddenly the Boolean shading works in either mode.
Exact steps for others to reproduce the error
Use BoolTool to create a brush bool difference of two cubes.
Shade the cut cube with principled shader, plug a noise texture into the color.
switch the bool method to exact.
The cut section (or merged) will not have any texture.
This works in either EEVEE or Cycles.Boolean error 3.2.2.blend
