Short description of error
Whenever I use the Boolean modifier the UV mapping is canceled, and the geometry turns white on the LookDev Viewport; it doesn't work on the Rendered Viewport either. When you enter edit mode, the texture is back and mapped correctly. As soon as you leave edit mode, the geometry goes blank again.

I figured out this was caused by the boolean modifier when I removed it and the texture got mapped correctly again. It is also fixed when you apply the modifier and then unwrap the texture again.

Exact steps for others to reproduce the error
The .blend file is too large, so I'm sendint printscreens showing the error.

Bug Report 01 shows the blank geometry with four boolean modifiers. As you can see, there are other textures on the scene that are mapped correctly.
Bug Report 02 shows the edit mode, where the texture is correctly mapped and all the modifiers are active.
Bug Report 03 shows the same geometry right after I deleted all the boolean modifiers. As you can see, the geometry is correctly mapped again.
