Thank you for reporting this issue. We will be triaging your incoming issue as soon as possible.
Hi, thank you. We'll take a look.
I have reviewed this a little bit. I took the latest source, and used PnP PowerShell 1.4.
I was able to add the personal calendar web part to the home page. However, I believe the reason for your error is because there is another Web Part with MGT (something like Personal Tasks) already on the page. (You have to remove the tasks web part, publish, refresh and add the calendar). In the current version of MGT (Microsoft Graph Toolkit) within the Starter Kit. It only allows 1 MGT web part on a page at a time. This is fixed in the upcoming release release of MGT... and we'll update MGT in the Starter Kit and this error should go away.
Here is the calendar on the home page, after removing the other MGT Web Parts.

@bcameron1231 Thanks for taking a look. That was the issue. Had the My Tasks web part in another area of the page. Looking forward to the day when we can put both of the web parts on the page at the same time.
Me too! We'll get these updated with new versions of MGT so we can support it!
@bcameron1231 We are running into this issue as well. Could you estimate when the next release will be published? Thank you.
Edit: Ah nevermind. MGT is also waiting - for the next version of SPFx 馃槰
Yes, as mentioned, we are waiting for the Graph team to release an update for MGT, which in turn they are waiting on updates. No eta on our side at this time unfortunately.
