I am doing an openSAP course - Building Applications with SAP Cloud Application Programming Model.
the business application studio was working fine so far.
But from past 5 hrs, I only see it is "STARTING" status. It didn't start running for the last 5 hours

I have tried clearing all browser cache, even cleared full browser history, still, I see only STARTING, the status is not changing to running at all.
I have also tried deleting the Spaces and created new multiple times, still no help.
Is there any planned downtime for SAP Business application studio on Sunday? I was working fine till noon from the past 1 week.
can anyone please help
