Sudden change in model with building materials and cannot move any elements

[Nadinehmk]

I've been working on the layouts of my model, and a sudden change in building materials (weak/strong) was made without me touching anything... I also cannot move anything, only the attraction points seem to be moving but not the elements themselves. I feel like a setting has been changed but I cannot seem to find what it is ? I've already tried changing the building materials, but nothing has worked. The model was perfectly fine. Nothing to do with the renovation filters either.

Operating system used: Mac Apple Silicon Sequoia 15

Have you tried turning it off and on again? OR even rebuilding the view?

Are you far away from the zero point?  The selection looks like it.

If nothing else works you could start a new file and merge this into it (File/interoperability/merge) 

You'll have to do the layouts and views again but at least you've got the model straight.
