Getting Started - iOS app crashes on launch

Question

Hi, I'm new to xamarin and have been working on getting setup to develop for iOS from a windows machine (I don't have a mac). I have gotten the same issue on two different machines, where I have been able to deploy to the phone, and everything seems fine up to the point that visual studio asks me to start the app to begin debugging. When I click the app, I get the Xamarin splash screen and then the app crashes or closes.

Here is what I have done:

1. I'm running the newest Visual Studio preview and xamarin tools. (see the bottom of the post)
2. Verfied iphone 6S reports it is up to date with iOS14.4
3. I registered a paid apple developer account, which now shows as active
4. Installed ITunes through the microsoft store and signed into my account. When prompted by the phone chose to trust the computer.
5. I verified Hot Restart and Hot Reload are both enabled
6. Used visual studio to generate a template xamarin cross platform app and verified the app builds and runs under the android emulator.
7. I turned on automatic provisioning in iOS Bundle Signing. I signed in w/ my dev account and have my individual team selected.
8. Selected my phone for the iOS app and told it to run. It deploys, showing up on the phone, and only gets to the xamarin splash screen before crashing.
9. I repeated this on a second PC.

Some other things I checked / noticed:

• I see my phone on the devices page of my developer account.
• With one of my PCs, visual studio only seems to intermittently detect my phone.

Any help would be greatly appreciated as I don't have any idea how to start troubleshooting this. I'm trying to spin up a proof of concept for an app that uses bluetooth, so I need to be running on actual hardware to make much progress. Thanks!
