Weird error after inserting a mesh

Ok, so i recently inserted a new mesh into roblox, after this, my studio went black, no screen guis, restarting studios doesn’t help, i tried deleting the meshes then undoing it, and it came up with an weird error
can someone help me?

Do you mind sharing/showing what the mesh you were trying to import was? That may help us figure it out.
