I'm having trouble with the boolean modifier. theres this weird artifact that shows after I have picked the object to cut out the other mesh. enter image description here

the highlighted is the object that will cut out that plane box underneath. if I hide that, it shows this. enter image description here

here are my setting for the boolean modifier enter image description here

I don't understand why this is showing. I even tried to edit the cylinder to make sure that it doesn't have overlapping faces. But when I do, the boolean doesn't even work. please help :'>

heres a close up at the weird artifact. enter image description here

It looks like you shoud recalculate normals (SHIFT+N).

Also you may need to enable Auto Smooth (in Object Data Properties > Normals) and adjust the angle to improve shading.
