Export-AzResourceGroup - An error occurred while sending the request. Line 55

[Svyatk0]

Hiya. i have used this tool successfully few days ago visualizing the exact same resource group.
Today all of a sudden i am getting the below error. I am running this in Win11

I have tried signing out and back in, switching back to PWShell 7.2 but without success, reinstalling
for some smaller groups it still works but for the larger ones (~50 resources) i am now getting this error.
Any suggestions/help appreciated.
