Once Synthesis placement cts_sta is completed, is it possible to start from resizer or all steps have to be completed again using new configuration parameters

There is the following Error
[ERROR GRT-0119] Routing congestion too high. Check the congestion heatmap in the GUI and load /media/psf/Home/Downloads/sljt1.comp.xfer/backupcvs/hcb1/hcb/LDPCENCDEC/openlane/ldpcEncDec/runs/24_03_18_20_16/tmp/routing/resizer-routing-design-congestion.rpt in the DRC viewer.
Error: resizer_routing_design.tcl, 46 GRT-0119
child process exited abnormally

check why/where congestion occurs.
Based on congestion you've start from floorplan/placement stage again

I would like to know how I can start from floorplan
I generally do
make user_proj_example
which runs from linting
