the course version changed from 4.14 to 4.18 and the lab wont't start
# lab start persisting-mounting
=> Error: No active course found. Please install and activate the course first...
? I can start and stop the entire environment but any lab start commands does not work

There is a wait time of 20-30 mins before you can run any lab script post the activation of your lab VMs. You can ssh to utility vm from workstation as lab user that is ssh lab@utility and run ./wait.sh to check if your OCP cluster is up or not. Wait for the script to finish and then you can run the lab start script. Better do this after recreating a fresh lab environment.
