I also had this issue, and it seems to be a bug with the launch file because the default namespace is blank, which causes the following argument to be taken as the namespace.

Try adding "namespace=:=tb3 use_namespace:=True" to the end of your launch, like:

ros2 launch nav2_bringup tb3_simulation_launch.py namespace=:=tb3 use_namespace:=True
