All stops disconnected

[zealous crater]

Hello everyone, hopefully you can help me.
I have been creating a new district, its going to be a capital city. So the idea is to have a lot of people, transport and services.
Designed the city created the all roads, set up power, water and all the metro lines and started the simulation again. At this point everything was working correctly.
The city has a central station, I initially used Multi-Level Metro hub and later I notice the Metro Plaza Station was much cooler, so I changed the configuration.

After the change I notice that some of the stops were not working, I assumed that the metro didn't reach the stop yet.
Then I notice that none of the stops in the game were working (bus, train and metro).
I tried to change the station back but it didn't work.

Do you have any suggestion what could be happening?
I tried to use the Broken Node Detector mod, but it didn't detect any problem. Also, I notice the game is laggy, it didn't happen before.

I have attached my mods list as a reference.

Thanks

Adding to the problem it seems that all the sims got hung.
Hearses, police and firemen are taking too long to response the request.
Also the trucks don't know how to access the buildings.

I feel that Phil had the same problem on one of the builds, but I don't remember.

did you add in any of the new quay walls?

I created a small lake in the middle of the city with the quay with trees

okay, so for experimentation, try delete the quay walls and see if you can notice any dramatic improvement
