Dear Customer,
Good day. Thanks for posting in the Microsoft Community.
Regarding your query about "How can I create a Power Automate cloud flow from a group calendar to a list that is on SharePoint?", hope your kind understanding that this query is required support from Power Platform team which is different from us.
We sincerely recommend you try to use your admin account to create a support ticket in the Power Platform admin center to get self-help solutions in real-time for their issue. If the issue can't be resolved through self-help, you can use the same Help + support experience to contact a Microsoft support representative. The support team over there has more resources and correct escalation channel in handling this kind of issues. This would be a more efficient way in handling the case for you. You can raise support ticket from Power Platform admin center
For reference: Get support | Microsoft Docs
