DefenderXDR "Preparing new space for data and connecting them" is stuck , and never finished !

Hello everyone, 
I am delivering SC-200 courses and on the lab environment of Skillable (or even free-tiers) when you have to "initiate" the data space for DefenderXDR, the process seems to be stuck .... never finished and we are "locked" in the page of a ...coffee cup and the phrase
"Hang on. We are preparing new spaces for your data and connecting them. "

does anyone else have same problem ? 
Any resolution , (I have already open a support ticket to Skillable support, but I haven't got resolution for over 1+day , and cannot open or continue the lab (for connecting or onboarding Microsoft Defender for Endpoint )  which is frustrating for the participants-students

Thanks
Panos
