Com.docker.slirp is using my container's ports

Docker Desktop

Expected behaviour

Can start my containers

Actual behaviour

Containers fail to start because docker has already allocated the same ports.

Still nothing.

I needed to get some development work done, so tried the docker reset:

Docker > preferences > reset to factory defaults.

After this the containers were rebuilt and they started correctly. The ports are still assigned to slirp but the containers are working correctly.

I suspect that this is a duplicate of:
