I would like the cloth to fall and hit the bricks, but it just passes through. I've replaced the bricks with a rigid cube before and it does the same thing. Am I missing something? I'll include the file and a GIF.

When I asked to simplify the blend, I ment to keep one example of cloth, only bricks that directly collide with cloth, there is no need to keep brick with a huge amount of vertices for this issue, so Decimate modifier could be applied (it slows down calculation any time you run simulation). You have also set Fake User for many objects. When deleted from a scene, they are still a part of file. To get rid of them you have to go into Outliner > Ophan Data > uncheck all of them and hit Purge. If objects are still there you can select them manually with Shift and with right-click choose Delet. Like that you can go from 184 MB to just 4 MB for a blend you could share with us (saved with compression enabled).
If you set Rigid Body just for colision with cloth (and you don't plan to destroy a wall later), it would not work. You have to enable Collision that you can find above Cloth Simulation.
